Description

  The present invention relates to a bucket conveyor, and more particularly to a bucket conveyor configured endlessly in a conveying direction by connecting a large number of buckets formed in a container shape so as to be rotatable by a connecting rod.

  Patent Document 1 discloses a bucket conveyor that is configured endlessly in the transport direction by connecting a large number of buckets adjacent to each other in a row in the transport direction of the object to be transported and pivotally connecting them with connecting rods. ing.

By the way, a bucket conveyor is used not only for conveying only one type of object to be conveyed, but also as a conveyor for conveying different kinds of objects to be conveyed. For example, in food processing plants, food materials such as soybeans, red beans, coffee beans, bread crumbs, curry powder, rice, wheat, bonito, refined salt, and granulated sugar can be used for several hours to several hours. Used for transportation from a material supply place to a food processing line over a period of days.
Therefore, for example, when curry powder is transported next after transporting bread crumbs according to the production lot, it remains attached to the inside (inner surface) of the bucket and the conveyor frame due to quality and hygiene. It is necessary to clean the inside of the bucket, the conveyor frame, and the like using liquid and / or gas in order to wash off the attached matter and the like.

Therefore, conventionally, cleaning nozzles, air nozzles, etc. are respectively arranged at the main points of the conveyor frame, and when the object to be transferred is changed, high pressure washing water is directed toward the inside of the bucket or the conveyor frame. Attempts have been made to wash off deposits and the like by spraying, and to blow away cleaning water by jetting air blow or the like.
Japanese Utility Model Publication No. 6-38014 (see Claims for Utility Model Registration, Paragraph Nos. 0008 and 0012, and FIGS. 1 to 6)

However, the cleaning with high-pressure cleaning water from the cleaning nozzle is limited, and the deposits cannot be completely removed.
For example, although it can be washed away by applying high-pressure line clean water accurately to the attached part that is attached to the exposed inner and outer surfaces of the bucket, the inner corner part (corner part) of the bucket or overlapping The adhering matter adhering to the superposed portion between the front bucket and the rear bucket in the conveying direction cannot be completely washed away and the improvement has been demanded.

  In addition, conventionally, a group of endless buckets has become an obstacle when jetting high-pressure washing water or the like toward the inner surface of the conveyor frame, and for that reason, the deposits adhered to the inner surface of the conveyor frame, etc. The current situation is that it cannot be washed off and removed.

  Therefore, the present invention has been developed to solve the above-described problems, and a large number of buckets are adjacent to each other in a row in the transport direction and are rotatably connected by a connecting rod having a length in the transport width direction. It is a bucket conveyor configured endlessly, and attached to the inside of the bucket, the conveyor frame, in particular, the inner corner portion of the bucket or the overlapping portion of the front bucket and the rear bucket in the transport direction. It is an object of the present invention to provide an improved bucket conveyor that can reliably wash off and remove kimono and the like.

In order to solve the above-mentioned problem, in the present invention, a large number of buckets are arranged in an endless shape by being adjacent to each other in a row in the transport direction and rotatably connected by a connecting rod having a length extending in the transport width direction. A bucket conveyor,
Both end portions of each connecting rod are provided with endless bucket moving bodies that are connected in a substantially ladder manner in the transport direction at the connection intervals of the buckets, and the buckets are provided on the front and rear side walls in the transport direction. A connecting portion with the connecting rod is provided, and the front connecting portion and the rear connecting portion are provided with a rod connecting concave portion that is detachably fitted to the connecting rod from the outer peripheral direction of the connecting rod. It is characterized by being.
Here, the rod connection concave portion of the rear connection portion is formed in a substantially U shape in a side view along an arc line drawn by a radius with the rod connection concave portion of the front connection portion as a base point. Is suitable.

With such a configuration, when a large number of buckets are mounted inside the conveyor frame, the respective rod connection recesses of the front connection part and the rear connection part of each bucket of the front bucket and the rear bucket in the transport direction, For each connecting rod that is connected and supported in the transport direction by the bucket moving bodies on both sides, by repeatedly aligning and fitting from the outer peripheral direction of the shaft, each bucket is connected endlessly in the transport direction, and the bucket machine frame Can be installed inside.
And when taking out a bucket from the inside of a conveyor machine frame, each bucket is lifted in the direction which makes each rod connection recessed part of the front side connection part and rear side connection part of each bucket detach | leave from a connection rod.
At this time, first, the rear bucket is rotated by using the front connecting portion (connecting rod) of the rear bucket connected to the rear connecting portion of the front bucket in the transport direction by the connecting rod, and the rear bucket is rotated. The rear connection part is detached from the connection rod with the front connection part of the next rear bucket, and then the front connection part of the rear bucket as a rotation fulcrum is connected from the connection rod with the rear connection part of the front bucket. By performing these series of operations for separation, all buckets connected endlessly in the transport direction can be removed from each connecting rod.
Thus, since the bucket can be taken out of the conveyor frame and cleaned using hand washing or a dedicated cleaning device, it is possible to clean the deposits completely from the inner and outer surfaces of each bucket.

Also , the inside of the conveyor frame from which all the buckets have been removed is in an almost empty state where only the connecting rods and the bucket moving bodies on both sides connecting the connecting rod groups in a substantially ladder shape in the transport direction remain. Thus, it is possible to perform cleaning in which the deposits adhering to the inner surface of the conveyor frame are quickly washed away by the high-pressure cleaning water from the cleaning nozzle of the cleaning device provided in the main part of the conveyor frame.
That is, the high-pressure cleaning water sprayed from the respective cleaning nozzles at the main points of the conveyor frame toward the target direction to be cleaned does not have a bucket as an obstacle, so that the deposits are reliably washed away.

  Further, in the present invention, a guide member that guides the bucket moving bodies on both sides in the transport direction is provided, and when the bucket is removed from the connection rod, the connection rod is connected to the front connection portion of the bucket. A rod pressing member for preventing movement in the direction of detachment from the rear connecting portion is provided.

  With such a configuration, as described above, when the front side connecting portion and the rear side connecting portion of each bucket are separated from the connecting rods of the front bucket and the rear bucket adjacent in the front and rear in the transport direction, It is possible to prevent the rod pressing members from moving so that the connecting rods are lifted in the direction in which the rod connecting concave portions of the front connecting portion and the rear connecting portion are separated from the connecting rod. Thereby, each bucket connection recessed part of the front side connection part of a bucket and a rear side connection part can be easily and rapidly detach | leave from a connection rod, and each bucket can be removed from each connection rod.

Since the bucket conveyor of the present invention is configured as described above, the bucket conveyor adheres to the inside of the bucket, the conveyor frame, in particular, the inner corner portion of the bucket, the outer surface overlapping portion of the front bucket and the rear bucket in the transport direction, and the like. The attached deposits can be washed out of the conveyor frame using hand washing or a washing device.
As a result, the deposits can be reliably removed from the inner and outer surfaces of the bucket, which is effective in managing the quality, hygiene and the like associated with the change of the transported object.

  In addition, according to the present invention, as described above, the bucket can be taken out of the conveyor frame and cleaned, so that the attached matter such as the inner surface of the conveyor frame can be removed from the conveyor. Since it can be reliably washed off and removed by high pressure washing water, air blow, etc. from the washing nozzles in the interior of the machine frame, it is effective not only for the bucket but also for the management of the internal hygiene of the conveyor machine frame.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings as appropriate.

≪Bucket configuration≫
4 is a longitudinal side view showing the bucket, FIG. 5 is a front view of the bucket as viewed from the front side in the transport direction, and FIG. 6 is a view of the bucket from the rear side in the transport direction. FIG. 7 is a plan view of the bucket. Here, description will be made with reference to FIG. 1 as appropriate.
In FIG. 4, the left side of the paper is the front in the transport direction, and the right side of the paper is the rear in the transport direction. In FIG. 5, the horizontal direction on the paper is the conveyance width direction.
The bucket 1 is integrally formed by injection molding using a desired molding material such as a synthetic resin material.
As shown in FIGS. 4 and 5, the bucket 1 has a lower front side wall 1a in the transport direction, a higher rear side wall 1b, and a front side wall 1a and an upper half side of the rear side wall 1b facing forward in the transport direction. And is formed in a substantially horizontally long rectangular box shape (box shape) long in the conveyance width direction in a plan view in which the bottom wall 1c side is curved.

Then, as shown in FIGS. 4 and 5, the bucket 1 is rearward at the height of the rear side wall 1 b from the upper end of the opening of the front side wall 1 a (rear in the conveying direction). 1d) having both side walls 1d extending in a substantially horizontal shape.
As shown in FIG. 7, the both side walls 1d include a continuous wall 1d-1 that connects the front side wall 1a and the rear side wall 1b, and an extended wall 1d- that extends rearward from the rear side wall 1b. The extended wall portion 1d-2 is positioned on the outside by the wall thickness from the continuous wall portion 1d-1 and extends rearward from the rear side wall 1b. That is, the continuous wall portion 1d-1 and the extended wall portion 1d-2 are connected in a stepped manner in plan view with the rear side wall 1b as a boundary.
Thereby, when each bucket 1 is connected endlessly in the conveyance direction, as shown in FIG. 9 described later, the extension wall portion 1d-2 of the front bucket 1-1 in the conveyance direction becomes the front bucket 1-2. It is made to superpose | polymerize on the outer side of the continuous wall part 1d-1. That is, by adopting a polymerization structure in which the extension wall portion 1d-2 is polymerized on the outside of the continuous wall portion 1d-1, the endless connection in the transport direction of the baguette 1 group is changed between the front and rear by the connecting rod 2. In cooperation with the connection, the connected state of the bucket 1 group is configured to move parallel to the conveying direction such as a belt conveyor.

  And the bucket 1 formed in this way is provided with front and rear connecting portions 16 and 17 for the connecting rod 2 on the front side wall 1a and the rear side wall 1b, respectively.

≪Configuration of front connection part≫
As shown in FIG. 5, the front side connecting portion 16 is formed with an appropriate width (length) from each end surface portion on both sides of the upper end of the opening of the front side wall 1 a of the bucket 1. And this front side connection part 16 is provided with the rod connection recessed part 18 for fitting and latching to the connection rod 2 from the axial outer peripheral direction so that attachment or detachment is possible.

The rod connecting recess 18 includes a rod hooking portion 18a at the back of the groove for hooking the shaft outer peripheral surface of the connecting rod 2, and a rod insertion portion 18b extending from the rod hooking portion 18a to the front downward opening. The latching convex part 18-1 which is mutually formed in an inward convex shape is provided in the boundary part. That is, the latching convex portion 18-1 is formed in an inward convex shape so that the entrance from the rod insertion portion 18b to the rod latching portion 18a is narrower than the shaft diameter of the connecting rod 2.
As a result, the connecting rod 2 inserted from the rod insertion opening 18b toward the rod latching portion 18a pushes and spreads between the latching convex portions 18-1 against the elastic action (spring action). It engages with and engages with the engaging portion 18a. In other words, when the connecting rod 2 is fitted into the rod latching portion 18a and latched, the latching convex portion 18-1 is configured so that after the coupling rod 2 passes, the coupling rod 2 is grasped by the restoring force. Returning to the state, the shaft outer peripheral surface of the connecting rod 2 can be firmly held so as to prevent the connecting rod 2 from being inadvertently dropped under a resilient action.

  Then, the rod insertion portion 18b that opens forward and downward has a predetermined inclination angle θ that is downward toward the front in the transport direction from a line that is directly below the base point P with the axial center of the rod hooking portion 18a as a base point P. Is formed.

Although it does not specifically limit as downward inclination angle (theta) toward the front of the conveyance direction of the rod connection recessed part 18, In this embodiment, it sets to the range of 35-55 degrees. In particular, setting to 45 ° is preferable.
As a result, when the bucket 1 is removed from between the connecting rods 2 in the front and rear directions in the transport direction, the rear side of the bucket 1 with the rod hooking portion 18a of the rod connecting recess 18 as a rotation fulcrum as shown in FIG. An operation of pulling up the bucket 1 substantially upward is performed at a rotation position obtained by rotating the bucket 45 ° in a direction (counterclockwise direction) in which a rod connection recess 19 described later on the connection portion 17 side is detached from the connection rod 2. In this way, the rod connecting recess 18 of the front connecting portion 16 can be detached from the connecting rod 2.
That is, the bucket 1 is transported by separating the front connection portion 16 of the bucket 1 from the connection rod 2 by a series of separation operations with the rotation of the bucket 1 for separating the rear connection portion 17 of the bucket 1 from the connection rod 2. It can be removed from between the connecting rods 2 in the front and rear directions.

  Moreover, as shown in FIG. 4, the rod insertion part 18b of the rod connection recessed part 18 is made into the substantially C shape by the side view gradually expanded toward the front downward opening from the rod latching | locking part 18a. Thereby, the alignment insertion operation when fitting and engaging the connecting rod 2 from the outer peripheral direction of the shaft can be performed easily and quickly.

≪Configuration of rear connection part≫
As shown in FIG. 4, the rear side connecting portion 17 is formed on each side wall 1 d extending rearward from the rear side wall 1 b of the bucket 1. The rear side connecting part 17 is provided with a rod connecting concave part 19 for fitting and engaging with the connecting rod 2 detachably from the outer peripheral direction of the shaft, like the front side connecting part 16.

  As shown in FIG. 4, the rod connecting recess 19 is formed in a substantially U shape in a substantially downward side view. The rod connecting recess 19 includes a rod hooking portion 19a at the back of the groove for hooking the shaft outer peripheral surface of the connecting rod 2 and a rod insertion portion 19b extending from the rod hooking portion 19a to the downward opening. Similarly to the rod connecting concave portion 18, the boundary portion is provided with latching convex portions 19-1 that are formed inwardly projecting from each other, and the connecting rod 2 is subjected to a resilient action (spring action). The shaft outer peripheral surface of the connecting rod 2 can be firmly held so as to prevent inadvertent dropping.

Then, as shown in FIG. 4, the rod insertion portion 19b extending from the rod engagement portion 19a to the downward opening has a rod engagement portion 16a at a radius π with the rod engagement portion 16a of the front connection portion 16 as a base point P. Are formed in a circular arc shape along the circular arc line Y drawn around the axis.
As a result, as described above, the bucket 1 is rotated in the direction in which the rod connecting recess 19 of the rear connecting portion 17 is detached from the connecting rod 2 with the rod hooking portion 16a of the front connecting portion 16 of the bucket 1 as a rotation fulcrum. It can be moved.

  Further, as shown in FIG. 4, the rod insertion portion 19b of the rod connecting recess 19 is gradually expanded from the rod hooking portion 19a toward the downward opening along the arc Y, similarly to the rod insertion portion 18b. In the side view, it has a substantially C shape. Thereby, the alignment insertion operation when fitting and engaging the connecting rod 2 from the outer peripheral direction of the shaft can be performed easily and quickly.

≪Configuration of bucket moving body≫
FIG. 8 is a perspective view showing a part of a state in which both ends of the connecting rod are supported by the left and right bucket moving bodies. Here, description will be made with reference to FIGS. 1 and 4 as appropriate.
As shown in FIG. 1, the bucket moving body 3 connects the connecting rods 2 that endlessly connect the bucket group 1 over the entire length of the transport line in a ladder shape in the transport direction with a connection interval of the bucket 1 group. Thus, the bucket 1 group receives the power of the driving sprocket 4 and sequentially moves the bucket group in the transport direction.
This rod connecting body 3 is formed into a belt having an appropriate thickness and width using a synthetic resin material or other material that has moderate flexibility (flexibility) and is excellent in corrosion resistance and durability. As shown in FIG. 1, the sprocket 4 is formed in an endless shape having a length spanned from the drive sprocket 4 on the conveyance end side to the idle sprocket 6 in the middle of conveyance to the turn sprocket 5 on the conveyance start end side. .
And this bucket moving body 3 is equipped with the rod adhering part 20 for adhering the both ends side of the connection rod 2, and connecting the connection rod 2 whole as shown in FIG.

  The rod fixing portion 20 is a connecting interval of the bucket 1 group, that is, as shown in FIG. 4, the dimension between the rod engaging portions 18a and 19a of the front connecting portion 16 and the rear connecting portion 17 of the bucket 1 unit. Each of the bucket moving bodies 3 on both sides is provided with an interval L, and is formed in a hole shape having an inner diameter corresponding to the shaft diameter of the connecting rod 2 as shown in FIG.

Although not shown, as shown in FIG. 3, the stopper after the end of the connecting rod 2 is inserted into the rod fixing portion 20 so as to protrude appropriately from the rod fixing portion 20 is a rod. This is performed by attaching a snap ring (E-shaped ring) or an appropriate stopper member such as a washer and a split pin to the protruding base from the fixing portion 20.
Further, the end of the connecting rod 2 can be fixed to the rod fixing portion 20 by adhesion, or a metal collar or the like can be attached to the rod fixing portion, and the end of the connecting rod 2 can be crimped by this collar.

Moreover, in this embodiment, as shown in FIG.1 and FIG.3, it forms in predetermined length in the lower horizontal conveyance part a-1 of the conveyor machine frame a in which the attachment / detachment port 12 of the bucket 1 is opened. Rod presser rails 21 as rod presser members are provided in parallel with the guide rails 9.
Thus, as shown in FIG. 11, when the bucket 1 is removed from the connecting rod 2 before and after the conveying direction, the connecting rod 2 moves in the respective detaching directions of the front connecting portion 16 and the rear connecting portion 17 of the bucket 1. I try to prevent that. That is, the operator holds the bucket 1 with one hand or both hands without pressing the connecting rod 2, and performs a detaching operation to move the bucket 1 in the detaching direction of the front connecting part 16 and the rear connecting part 17, The bucket 1 can be removed from between the connecting rods 2 before and after the conveying direction and taken out of the conveyor frame a.

[Description of action]
Next, the operation of the bucket conveyor according to the present embodiment configured as described above will be briefly described.
9 and 10 are an enlarged vertical side view and a plan view showing a part of the state where the bucket is attached to the connecting rod supported and connected to the left and right bucket moving bodies, and FIG. It is explanatory drawing which shows the operation procedure when removing a bucket from the state of FIG. Here, description will be made with reference to FIGS. 1 and 3 as appropriate.
When the bucket 1 is removed from the connecting rods 2 connected in a ladder shape before and after the conveying direction, first, as shown by a two-dot chain line in FIGS. 1 and 3, the opening / closing lid 14 that closes the attachment / detachment opening 12 is opened. .

  Next, as shown in FIG. 11A from the state shown in FIG. 9, the rod latching portion 18 a (front engaging portion 16 connected to the rear connecting portion 17 of the front bucket 1-1 in the transport direction ( The bucket 1 is rotated counterclockwise (in the direction of the arrow M1) with the connecting rod 2) as a rotation fulcrum, and the rear connecting portion 17 is connected to the front connecting portion 16 of the rear bucket 1-2. Let go. At this time, the rod connecting concave portion 19 of the rear side connecting portion 17 is formed in an arc shape with a radius starting from the rod hooking portion 18a of the front side connecting portion 16, thereby smoothly rotating the bucket 1. Can be done.

In the state in which the rear side connecting portion 17 of the bucket 1 is released by such a detaching operation, the rear bucket 1-2 located at the rear of the bucket 1 is also connected to the front side connecting portion 16 as shown in FIG. By rotating the rod latching portion 18a in the counterclockwise direction (in the direction of the arrow M2) using the pivoting fulcrum, the rear connecting portion 17 is detached from the connecting rod 2 with the front connecting portion 16 of the rear bucket 1-2. .
In this way, by performing the operation of pulling up the rear bucket 1-2 to be removed substantially obliquely upward (in the direction of the arrow M3) after detaching the rear connecting portion 17 from the connecting rod 2 with the front bucket 1-2. The bucket 1-1 can be taken out of the conveyor frame a by detaching the rod connecting recess 18 of the front connecting part 16 from the connecting rod 2 with the rear connecting part 17 of the bucket 1 (FIG. 1 and FIG. 1). 3).
That is, each bucket 1 is simply removed from between the front and rear connecting rods 2 that are connected and supported in a ladder shape by the bucket moving bodies 3 on both sides, and all the buckets 1 are removed from the conveyor frame a in a short time. Can be taken out.

Thereafter, the rotation in the counterclockwise direction (arrow M2 direction) shown in FIG. 11 and the pulling up operation substantially obliquely upward (arrow N3 direction) are sequentially repeated, and finally the front bucket 1-1 is moved substantially obliquely upward ( All buckets 1 can be taken out of the conveyor frame a by performing a detaching operation of pulling up in the direction of arrow N3).
Thereby, all the buckets 1 are taken out from the inside of the conveyor frame a, and are attached to the inner corner portion of the bucket 1 or the outer surface overlapping portion between the front bucket 1-1 and the front bucket 1-2 in the transport direction. Deposits and the like can be washed out of the conveyor frame a using hand washing or a washing device.

According to the bucket conveyor A according to the present embodiment configured as described above, when the bucket 1 is removed from between the front and rear connecting rods 2 connected in a ladder shape in the transport direction, as described above, first, The side connecting portion 17 is separated from the connecting rod 2 with the front side connecting portion 16 of the rear bucket 1-2 by turning counterclockwise (arrow M1 direction), and then the rear bucket 1-2 Each bucket 1 is moved out of the conveyor frame a unless the separation operation procedure for rotating and pulling the side coupling portion 17 side and the front side coupling portion 16 in the respective separation directions (arrow M2 direction and arrow N3 direction) is performed. The structure cannot be taken out.
As a result, during the conveyance of the object to be transported, each bucket 1 is attached to each connecting rod 2 so that the bucket 1 is not inadvertently detached from between the connecting rods 2 before and after the ladder. When the bucket 1 is connected endlessly in the transport direction (arrow X direction), and the bucket 1 is taken out of the conveyor frame a and cleaned using a hand-washing device or a dedicated cleaning device, the connecting rod is used in the above-described detachment procedure. The bucket 1 is removed from between the two so that deposits and the like can be washed off outside the conveyor frame.

The specific configuration of the embodiment of the present invention is not limited to the above-described embodiment, and there are design changes and the like without departing from the gist of the present invention described in claims 1 to 3. Are also included in the present invention.
For example, the bucket moving bodies 3 on both sides that support both ends of the connecting rod 2 can be changed from a belt system to a chain system. In this case, it is preferable to use a chain made of a synthetic resin material other than metal in terms of hygiene management.
Further, the length of the link plate unit constituting the endless shape of the chain is formed to a length corresponding to the coupling interval of the buckets, and the above-described implementation is performed on the front and rear end portions (hinge portion) in the length direction of each link plate unit. By providing a cylindrical rod fixing portion made of a pipe material or the like that is inserted and supported by the end portion of the connecting rod 2 as in the form, an endless chain is formed, and both end portions of the connecting rod 2 are connected to the rod fixing portion. It is preferable that the connecting rods 2 are connected and supported in a substantially ladder-like manner in the transporting direction with the connection intervals of the buckets 1 by the respective chains on both sides in the transporting width direction by inserting and supporting the portions. It will be a thing.

  Moreover, the 2nd latching recessed part 8 which latches the protrusion edge part of the connecting rod 2 can be provided only in the drive sprocket 4 side. Thereby, the belt-like bucket linkage body 3 can be reliably moved in the transport direction, and the bucket 1 group can be moved sequentially.

Further, as shown in FIG. 4, the rod insertion portions 18b and 19b of the rod connection recesses 18 and 19 of the front side connection portion 16 and the rear side connection portion 17 are not substantially C-shaped in a side view. Further, only the mouth side can be formed into a round shape or the like in parallel with the hole diameters of the rod retaining portions 18a and 19a.
Further, as the opening shape of the rod connecting recesses 18 and 19 in the side view of the rod insertion portions 18b and 19b, the mouth side is narrowed and the hole diameters of the rod engaging portions 18a and 19a toward the rod engaging portions 18a and 19a are set. It can be gradually formed so as to have substantially the same mouth width (U-shaped width).

Further, the rod connecting recesses 18 and 19 can be provided with an elastic promoting slit or the like for promoting an elastic action (spring action) if necessary and continuing the elastic action.
For example, an elastic promoting slit that is substantially parallel to the outer edge of the rod insertion portion 19b along the opening edge of the rod insertion portion 19b is provided in the vicinity of the connection from the mouth side of the rod insertion portion 19b to the rod hooking portion 19a. When the connecting rod 2 passes, it is elastically deformed in the direction in which the mouth width (U-shaped width) of the rod insertion portion 19b widens, and when the connecting rod 2 passes, the mouth width of the rod insertion portion 19b. The elastic action for elastically deforming in the closing direction (returning direction) can be maintained continuously.
