Description

  The present invention is a transfer conveyor suitable as a transfer line when processing such as washing, sterilization, heating and cooling of foods represented by vegetables and meat is continuously performed in a flow operation. The present invention relates to a transport conveyor in which deck plates are attached at a constant pitch between endless conveyor chains arranged in parallel, and a transport surface is configured by the deck plates.

  For example, in the case of washing while conveying vegetables and the like, a conveyor such as a belt conveyor, a net conveyor, and an apron conveyor has been conventionally used as a conveyor.

  As for the net conveyor, a net conveyor rail that can be cleaned without a blind spot has been proposed (see Patent Document 1 below).

JP 2004-115142 A

  Conveyors used for transporting food are required to be kept clean at all times, and cleaning including peripheral equipment is periodically performed in order to meet the demand. For example, in the case of a conveyor for a washing line for vegetables or the like installed inside the aquarium, the whole is taken out of the aquarium.

  The reason for adopting such a troublesome method is to reduce the number of blind spots for cleaning. If the conveyor is in the aquarium, there will be areas that cannot be cleaned or difficult to clean, and the entire area cannot be cleaned.In addition, the conveyor becomes an obstacle and the peripheral areas such as the bottom and inner side of the tank are cleaned. Therefore, the entire conveyor is taken out of the water tank in order to reduce the problem as much as possible.

  However, this method requires a large amount of work and requires equipment such as a crane for lifting the conveyor. In addition, since it is necessary to lift the entire conveyor, there is a problem in work safety.

  In addition, since the work becomes large, frequent cleaning is difficult. In addition, if the conveyor surface is a conveyor made up of belts or deck plates (conveyed items are less likely to be scratched and less likely to catch on the mesh than net conveyors), It is difficult to clean and it is difficult to clean the entire area.

  In addition, the net conveyor of the above-mentioned patent document 1 attaches the net receiving rail to the conveyor frame in a detachable manner, and by removing it, the net receiving rail can be cleaned without blind spots and the peripheral equipment and the conveyor frame can be easily cleaned. It is done.

  In this way, the conveyor can be disassembled (some elements are detachable) so that it can be cleaned without blind spots, but the belt conveyor cannot be disassembled and cleaned, and there are many conveyor surfaces. A conveyor composed of deck plates cannot be cleaned to meet the requirements unless all deck plates are removed.

  A conveyor that forms an endless transport surface with a large number of deck plates usually uses a dedicated conveyor chain with attachments for mounting the plates. Both ends of each deck plate are bolted to two endless conveyor chains arranged in parallel. It is attached with nuts. Therefore, the method of removing all the deck plates requires a lot of labor and labor.

  SUMMARY OF THE INVENTION An object of the present invention is to facilitate the cleaning of the conveyor and the peripheral area by making it possible to easily remove the deck plate of the conveyor whose conveying surface is constituted by the deck plate, and to make it possible to perform cleaning without blind spots. .

In order to solve the above problems, in the present invention, the conveyor is configured as follows.
That is, two sets of left and right drive sprockets and driven sprockets, two endless conveyor chains arranged in parallel, each of which is individually spanned between the left and right drive sprockets and driven sprockets, a deck plate constituting a conveying surface, and A deck unit composed of a movable frame that holds each deck plate individually, and a reversing mechanism that rotates the deck unit at the transport start end so that one end is in front of the transport direction;
The movable frame includes left and right vertical frames, a horizontal frame connecting the other ends of the vertical frames, and a plate insertion groove provided on each of the vertical frames so as to open to one end of each vertical frame and the inner surfaces facing each other. A pivot shaft that protrudes in a direction opposite to the side surface of each vertical frame and is inserted into a shaft hole provided at a constant pitch in the chain links of the left and right conveyor chains,
The movable frame is rotatably supported by the two conveyor chains with the pivot shaft as a fulcrum,
The deck unit is configured by inserting the deck plate into the plate insertion groove and detachably connecting to the movable frame with a connector.
The deck unit has different weights at one end and the other end with the pivot shaft as a boundary. The weight difference between the one end and the other end and the rotation of the reversing mechanism cause the leading edge of the succeeding deck unit. Overlaps the rear part of the preceding deck unit from above to create the forward transfer surface (hereinafter referred to as the first form).

  In addition, a guide rail that is continuously arranged in the longitudinal direction in the forward path and rotates the deck unit horizontally at the conveyance start end and is supported from below is installed, and the guide action by the guide rail is provided at the conveyance start end as necessary. In addition, the reversing mechanism rotates the deck unit in a horizontal posture at the starting end of the forward path, and the conveyor unit in which the deck unit after rotation is supported in the transport direction and supported by the guide rail to create the forward transport surface is also included. (This is referred to as the second form). In the transport conveyor according to the second embodiment, the weight on one end side of the deck unit with respect to the pivot shaft may be equal to the weight on the other end side.

  Note that the forward path referred to here is a side on which the conveyance is performed from the conveyance start end toward the conveyance end.

  The movable frame alone preferably has a weight on the other end larger than the weight on the one end with the pivot shaft as a boundary.

  Further, the reverse mechanism of the transport conveyor of the first form may be one that reverses the deck plate during movement using the relative movement of the member whose position is fixed to the pivot shaft and gravity.

  Furthermore, the connecting tool is provided with a pin hole corresponding to the position at the end of insertion of the deck plate into the plate insertion groove corresponding to the vertical frame and the deck plate, and one connecting pin is provided in the two pin holes. What maintains the connection state of two persons through is preferable. Of course, other connectors can be used.

  For example, a spring-engaged locking pin is provided on the movable frame, and the locking pin can be extracted from the pin hole provided in the deck plate at the position where the deck plate is inserted into the plate insertion groove to the end of insertion. It is also possible to connect the two members by engaging with each other, or a latch that engages the groove at a position where the deck plate is inserted into the plate insertion groove to the insertion end point.

  In this conveyor, blades and crosspieces can be provided on the deck plate to push the conveyed product. Further, an apron conveyor can be configured by attaching a side plate to the deck plate, and a draining hole or the like can be added to the deck plate as required.

  In addition, it is preferable that the transport conveyor according to the present invention is provided with a moving guide that guides the deck unit on the return path in a state close to a horizontal posture.

  Also, the conveyor of the washing line introduces the deck plate and the conveyor chain into the water tank at the transport start end side, and then tilts the transport end side of the transport conveyor forward and pulls it out on the water surface. It is preferable to adopt a structure in which the deck unit on the returning path is guided to the conveyance start end by tilting the deck unit so that one end side of the deck unit is behind the return direction.

  The present invention also provides a cleaning facility configured as such. When this cleaning equipment is used for cleaning a transported object that is easy to roll, it is preferable to provide blades or bars that push the transported object on the deck plate.

  In the conveyor according to the present invention, the deck plate is detachably connected to the movable frame with a connector, and the deck plate can be detached from the movable frame by releasing the connection by the connector. For removing the deck plate, for example, when the deck plate is connected to the movable frame by one connecting pin, it is only necessary to pull out one connecting pin. A device using a locking pin or a latch biased by a spring only needs to disengage the locking pin or the latch, and the operation is simple.

  As a result, it becomes possible to easily and reliably clean the back side of the transport surface (the back side of the deck plate), which has been difficult to clean in the past. Also, when the deck plate is removed, the surface of the peripheral area hidden under the conveyor and on the side appears on the front, so the peripheral area can be easily and reliably cleaned, facilitating cleaning and cleaning without blind spots. The objective is achieved.

  In addition, the transport conveyor of the first form is provided with a difference between the weight on one end side and the weight on the other end side with respect to the pivot axis of the deck unit, and a reversing mechanism for rotating the deck unit at the transport start end. As a result, the leading edge of the succeeding deck unit overlaps the other end of the preceding deck unit from above in the forward path, and a stable transport surface is formed.

  In this way, the leading deck unit has a force to rotate the other end side upward due to the weight difference between the front and rear of each deck unit, and the trailing deck unit has a force to rotate the one end side downward. Since these forces work to cancel each other out, the formed conveyance surface becomes stable. In addition, the preceding deck unit is prevented from suddenly rotating at the end of conveyance due to the overlap, and the trouble that the conveyed object is jumped off by the sudden rotation of the deck unit is also avoided.

  In the transport conveyor of the second form, the deck unit is supported in a horizontal position by the guide rail by the guide effect by the guide rail at the transport start end. Then, the deck unit is supported by the guide rail and aligned in the transport direction to create a forward transport surface.

  In addition, the movable frame constituting the deck unit alone can be easily re-inserted into the plate insertion groove of the deck plate by making the weight on the other end side larger than the weight on the one end side with respect to the pivot shaft. become. This is because when the deck plate is removed, the movable frame rotates with a weight difference between the one end side and the other end side, and becomes a vertical posture so that the plate insertion slot of the plate insertion groove faces upward.

  In addition, conveyors with vanes and crosspieces on the deck plate can push and move the conveyed items with the vanes and crosspieces, so that it is possible to stably convey conveyed items that are easy to roll, and it is possible to tilt the conveying surface upward. become.

  In addition, a device provided with the above-described movement guide moves by being tilted so that the return deck unit is inclined by the function of the movement guide. For this reason, it is not necessary to unnecessarily increase the height of the return path, and it is possible to reduce the size of the conveyor and the cleaning equipment using the conveyor.

  In addition, since the deck unit on the return path is moved by the conveyor chain, the movement of the deck unit on the return path is more stable as compared with the case of pushing the deck unit.

  Hereinafter, based on FIGS. 1 to 11 of the accompanying drawings, an embodiment of a transport conveyor of the present invention and a cleaning facility using the same will be described.

  1-6 has shown the conveyance conveyor of the 1st form. The conveyance conveyor 1 of this 1st form comprises a horizontal conveyance line.

  This conveyor 1 comprises a drive sprocket 2, driven sprocket 3, idle sprockets 4, 5, a conveyor chain 6 that spans between the drive sprocket 2 and the driven sprocket 3 via the idle sprockets 4, 5, and a conveyance surface. Reversal that rotates the deck plate 7, the movable frame 8 that individually holds each deck plate 7, and the deck unit 9 constituted by the deck plate 7 and the movable frame 8 so that one end side is in front of the conveyance direction at the conveyance start end. The mechanism 10 is combined.

  The drive sprocket 2 is rotationally driven by a drive source such as a motor with a speed reducer (not shown). Two sets of the drive sprocket 2 and the driven sprocket 3 are provided symmetrically, and an endless conveyor chain 6 is spanned between each set of the drive sprocket 2 and the driven sprocket 3 in parallel.

  As shown in FIG. 2, the illustrated conveyor chain 6 uses a roller chain in which a shaft hole 11 is provided in a chain link 6a. The shaft hole 11 may be formed in the attachment by providing an integral standing attachment on the chain link 6a. The shaft holes 11 are provided at a constant pitch in the longitudinal direction of the conveyor chain 6.

  The shaft hole 11 has an installation pitch that is an even multiple of the inter-shaft pitch of the conveyor chain, and a portion where the sprocket teeth do not enter the inside (the conveyor chain shown in the example allows the sprocket teeth to enter inside the inner link. Therefore, it is preferable that the outer link of the chain link is provided in a place where teeth do not enter.

  A large number of deck plates 7 and movable frames 8 are provided at a constant pitch. The deck plate 7 is formed only by a square flat base portion 7a {see FIG. 3 (a)}, and is provided with blades 7b standing on the upper surface (surface to be a conveyance surface) of the base portion 7a {FIG. 6 (a)}, or those provided with side plates 7c standing on both sides of the base portion 7a {see FIG. 6 (b)} are selected according to the purpose of use of the conveyor.

  The deck plate 7 is preferably one that is drained in a conveyor for cleaning purposes. When the material is a punching plate, expanded metal, or the like, the eye of the material becomes a draining hole. A deck plate formed of resin, hard rubber, or the like may be used, and a drain hole can be formed by molding.

  A crosspiece (not shown) for catching a conveyed product can be provided instead of the blade 7b. The blade 7b and the side plate 7c are installed at a position where the insertion of the base portion 7a into the plate insertion groove 8c (see FIG. 3) of the movable frame 8 is not hindered.

  The number of movable frames 8 is the same as the number of deck plates, and holds each deck plate 7 individually. As shown in FIG. 3A, the movable frame 8 includes left and right vertical frames 8a and 8a, a horizontal frame 8b connecting the other ends of the vertical frames, and left and right vertical frames 8a and 8a. Each of the vertical frames includes a plate insertion groove 8c that is provided open on the inner surface facing each other, and a pivot shaft 8d that protrudes in a direction opposite to the side surfaces of the vertical frames 8a and 8a.

  Both the vertical frame 8a and the horizontal frame 8b are formed of a channel material. When the horizontal frame 8b is used for a conveyor of a cleaning line, it is preferable to provide a draining hole 8e {see FIG. 3 (b)} at an appropriate position so that water does not accumulate in the groove.

  The movable frame 8 is rotatably supported by inserting a pivot shaft 8d into a shaft hole 11 formed in the chain link 6a of the left and right conveyor chains and using the pivot shaft 8d as a fulcrum. Note that the movable frame 8 used here has a weight on the other end side with respect to the pivot shaft 8d as larger than a weight on the one end side.

  The deck unit 9 is configured by inserting the deck plate 7 into the plate insertion groove 8 c of the movable frame 8 and detachably connecting to the movable frame 8 with a connector 12. The deck unit 9 has a weight on one end side with respect to the pivot shaft 8d as larger than a weight on the other end side.

  Further, when the reversing mechanism 10 described above is used, the deck unit 9 has the length L shown in FIG. 4 from the pivot shaft 8d to one end, and the pivot shaft 8d that has passed through the driven sprocket 3 is conveyed by the idle sprocket 4. It is set to a range in which the contact state on the one end side of the deck unit 9 with respect to the support shaft 13 is maintained at the position returned to the start end side (backward in the transport direction from the point Q in FIG. 4). In the illustrated deck unit 9, one end side is the forward path and the front in the transport direction.

  The reversing mechanism 10 uses a support shaft 13 supported at both ends by bearings (not shown) and an idle sprocket 4 on the upper side in the drawing close to the driven sprocket 3, and uses the movement of the deck unit 9 in the transport direction. Then, what is reversed is illustrated.

  The support shaft 13 crosses the conveyance path, and left and right driven sprockets 3 and 3 are fixed to the support shaft 13. The idle sprocket 4 of the reversing mechanism 10 is disposed below the driven sprocket 3 and at a position where the conveyor chain 6 turned by the driven sprocket 3 is returned to the conveyance start end side.

  The support shaft of the idle sprocket 4 is a cantilever support shaft and does not block the moving path of the deck unit 9.

  In the reversing mechanism 10, the pivot shaft 8d of the deck unit 9 moves together with the conveyor chain 6 at the conveyance start end, whereas one end side of the deck unit 9 hangs downward due to a weight difference from the other end side, 13 is subject to movement restrictions.

Therefore, when the pivot shaft 8d that has passed through the driven sprocket 3 is directed to the idle sprocket 4, the deck unit 9 naturally rotates due to the difference in weight before and after the pivot shaft 8d. The leading edge of the succeeding deck unit overlaps with the end side from above, and the intended transport surface is formed in the forward path.
The deck unit 9 may have a weight on one end side smaller than a weight on the other end side. In that case, the forward deck unit 9 in FIG. 1 has the rear side in the transport direction in front of the transport direction, and the movable frame 8 overlaps the deck plate of the preceding deck unit. Thus, the deck unit 9 may have either one end side or the other end side in front of the transport direction.

  The illustrated connector 12 is provided with a pin hole 12a penetrating in the plate width direction at the distal end of the deck plate 7 in the insertion direction into the plate insertion groove 8c, and further, with the pin hole 12a at the end of insertion of the deck plate into the plate insertion groove 8c. The pin holes 12b having the same position are provided in the movable frame 8, and a combination of these pin holes and one connecting pin 12c is illustrated.

  The connection pin 12 c is inserted into the pin holes 12 a and 12 b, and this pin maintains the connection state of the movable frame 8 and the deck plate 7. As the connecting pin 12c, a pin that is prevented from coming off from the pin hole, for example, a pin that has a head at one end and a yoke 12d at the other end, or a pin that locks a split pin or the like is used. The illustrated yoke 12d is inserted into a slit provided at the tip of the connecting pin 12c and attached to the connecting pin so as to be rotatable by the pin.

  This connecting tool 12 is provided with a locking pin or a latch claw urged in a locking direction by a spring on the movable frame 8, and the locking pin or latch claw is attached to the deck plate at the end of the deck plate insertion into the plate insertion groove 8c. The pin hole or groove provided may be detachably engaged to connect the two together.

  In the illustrated deck unit 9, the weight on one end side with respect to the pivot shaft 8d is larger than the weight on the other end side. Further, the movable frame 8 has a weight on the other end side with respect to the pivot shaft 8d being larger than a weight on the one end side.

  As a result, when the pivot shaft 8d that has passed through the driven sprocket 3 is returned to the front in the transport direction from the contact point of the deck unit with the support shaft 13, one end side of the deck unit 9 rotates clockwise in FIG. And the leading edge of the succeeding deck unit overlaps with the other end of the preceding deck unit from above, and the intended transport surface is formed in the forward path.

  The reversing mechanism 10 may be as shown in FIG. 7 or FIG. The reversing mechanism 10 in FIG. 7 is provided with a guide 10a around the support shaft 13, and movement restriction on one end side of the deck unit 9 is performed by the guide 10a. The distance from the center of the support shaft 13 of the guide 10a is larger than the radius of the support shaft 13, and therefore the reversal can be accelerated compared to the case where the deck unit 9 is reversed using the support shaft 13.

  Further, in the reversing mechanism 10 of FIG. 8, the pinion 14 fixed to the pivot shaft 8d is engaged with the position-fixed rack 15 at the conveyance start end, and the pivot shaft 8d is rotated by the rotation of the pinion 14 so that the deck unit 9 is rotated. Is reversed clockwise in FIG.

  The transport conveyor 1 of the first embodiment configured as described above is provided with the reversing mechanism 10 at the transport start end, so that in the forward path, the leading edge in the transport direction of the subsequent deck unit overlaps the other end side of the preceding deck unit from above, The overlapping state is continuous in the transport direction to create a series of transport surfaces. Since the conveying surface works in the direction where the rotational force is opposite to the overlapping portion of the preceding deck unit and the succeeding deck unit, vegetables and the like can be stably conveyed.

  Further, on the return path, the deck unit 9 rotates and hangs downward in such a manner that one end side is lowered due to the collapse of the weight balance before and after the pivot shaft 8d, and in this state, the deck unit 9 is returned to the conveyance start end.

  In the conveyor 1 of the first embodiment, the deck plate 7 can be removed by a simple operation of simply pulling out the connecting pin 12c, and therefore, the back side of the conveying surface (the back surface of the deck plate 7) can be cleaned without any trouble. Is possible. Further, when the deck plate 7 is removed, the surface of the peripheral area hidden under the conveyor or on the side appears on the front surface, so that the peripheral area can be easily and reliably cleaned.

  In addition, the movement guide 16 shown in FIG. 9 can be attached to the conveyance conveyor of this invention. The moving guide 16 turns at the end of conveyance of the conveyor and hangs down the return deck unit 9 that hangs down on one end side so that one end side is behind the return direction, and maintains the state until the conveyance start end. . Carriers such as rollers and balls that reduce the movement resistance of the deck unit 9 can be installed on the guide surface of the movement guide 16 as necessary.

  FIG. 10 shows the main part of the transport conveyor of the second form. The transport conveyor 1 according to the second embodiment is configured to create a forward transport surface without overlapping the preceding deck unit and the succeeding deck unit. The installation pitch of the deck unit 9 is larger than the length dimension of the deck unit 9 in the transport direction. In addition, a guide rail 17 that is continuous in the longitudinal direction of the forward path is additionally provided, and the deck unit 9 on the forward path is supported by the guide rail 17, thereby maintaining the transport posture of the deck unit 9 (attitude parallel to the traveling direction of the conveyor). Like to do.

  The deck unit 9 used in the transport conveyor 1 according to the second embodiment has the same weight on one end side as the boundary on the pivot shaft 8d and the weight on the other end side, and the weight on the one end side is larger than the weight on the other end side. The weight on one end side may be any smaller than the weight on the other end side. What is necessary is not to mix a heavy weight on one end side and a heavy weight on the other end side.

  In addition, by bending the starting end of the guide rail 17, the deck unit 9 can be placed in a horizontal posture using the guide action of the guide rail 17, and thus the reversing mechanism 10 is not an essential element. However, the reversing mechanism may be freely installed as necessary. Since the other structure is the same as the 1st form conveyance conveyor, description is abbreviate | omitted.

  The transport conveyor 1 of the second embodiment can also perform cleaning without a blind spot by removing the deck plate of the deck unit.

  Next, an example of the cleaning equipment constructed using the transport conveyor of the present invention will be described with reference to FIG. The illustrated cleaning equipment 20 is configured by combining the transport conveyor 1 of the above-described first form, a water tank 21, and a moving guide 16 installed on the lower side of the water tank.

  This cleaning equipment 20 is provided with a total of four idle sprockets 4 and 5 between each drive sprocket 2 and driven sprocket 3 of the conveyor 1, and two of these idle sprockets 4 are on the inlet side and outlet side of the cleaning line. The other two idle sprockets 5 are installed between the water tank 21 and the moving guide 16 on the inlet side and the outlet side of the cleaning line.

  The paired left and right conveyor chains 6 are spanned between the drive sprocket 2 and the driven sprocket 3 via the four idle sprockets 4, and a number of deck units 9 are placed on the left and right conveyor chains 6 in the conveying direction. Are pivotally supported at a constant pitch.

  The conveyor chain 6 and the deck unit 9 are introduced into the water tank 21 on the conveyance start end side, and portions other than the conveyance start end side and the conveyance end side are drawn below the water surface. In addition, the conveyor end-of-conveyance side is tilted in the upward direction and pulled out to the surface of the water tank, and the deck plate 7 that has passed through the position of the drive sprocket 2 is tilted by the moving guide 16 so that one end side is behind the return direction. To guide the transport start.

  The deck plate 7 returned to the conveyance start end is reversed by the reversing mechanism 10 so that one end side comes to the front side in the conveyance direction, and the conveyance surface formed in this way is introduced into the water tank 21 so that vegetables to be washed can be washed. It is transported and washed with water during the transport.

  The conveyor 1 may be a second type conveyor. This cleaning equipment 20 is provided with blades 7b that push the conveyed product on the base portion 7a of the deck plate that constitutes the conveying surface in order to reliably carry the conveyed item out of the water tank, but there is no fear of rolling, such as spinach. Conveyed items such as leafy vegetables can be carried out of the aquarium without blades or crosspieces.

  Further, the cleaning equipment 20 can use the water tank 21 as the movement guide 16 in combination. At this time, the conveyor chain 6 and the deck unit 9 are drawn into the water tank even in the return path.
