Description

  This invention is a conveyance conveyor suitable as a conveyance line when processing such as washing, sterilization, heating, and cooling of vegetables and meat is continuously performed in a flow operation, and more specifically, members constituting the conveyance surface are simplified. The present invention relates to a conveyor that can be removed and can clean the entire area of the conveyor and the surrounding area without any trouble.

  For example, when washing vegetables while transporting, a transport conveyor such as a belt conveyor, a net conveyor, or an apron conveyor has been conventionally used as a transport device.

  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 composed of a belt or a slat bar, it is difficult to clean the back side of the conveyor surface even if the conveyor surface is taken out of the water tank, and it is difficult to sufficiently 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 cleaning without blind spots can be performed, but the belt conveyor cannot be disassembled and cleaned. In addition, a conveyor configured with an endless transport surface by attaching a large number of slat bars to the left and right conveyor chains at a constant pitch cannot be cleaned in accordance with the requirements unless all the slat bars are removed.

  The conveyor which comprises a conveyance surface with a slat bar usually uses a dedicated conveyor chain having an attachment for attaching the bar, and each slat bar is individually attached to the conveyor chain with bolts and nuts. Therefore, the cleaning needs to be performed with all slat bars removed, which is very time consuming and labor intensive.

  It is an object of the present invention to make a conveyor having an endless conveyor surface easy to clean each part of the conveyor and the surrounding area without any blind spots.

In order to solve the above problems, in the present invention, the conveyor is configured as follows. That is, a plurality of endless conveyor chains arranged in parallel that are individually driven between a driving sprocket and a driven sprocket and synchronously driven, and a plurality of endless conveyor chains are attached to the conveyor chain at a predetermined pitch to form an endless conveying surface. Have a deck module that
The deck module is configured to be able to bend together with the conveyor chain at the start and end of a conveyor, and the deck module is attached to the conveyor chain so that the left and right of the front part in the transport direction and the left and right of the front and rear part in the transport direction are detachably attached to the conveyor chain. The deck module was received and supported by each of the conveyor chains in the forward path of the conveyor.

  The deck module is preferably one in which a plurality of deck pieces are sequentially hinged and connected in one direction. However, the net of the net conveyor is cut into a predetermined length, and a necessary portion of the net, for example, the transport direction. Even if the front part and the rear part are reinforced and the reinforcing part is attached to the conveyor chain, there is no problem. The point is that it can be bent together with the conveyor chain at the start and end where the direction of the conveyor is changed.

  The deck piece referred to here is a horizontally long track-like member that is sequentially hinged to form an endless transport surface, and includes a chain link having a special shape similar to the shoe plate.

  Both the deck module composed of a plurality of deck pieces and the deck module composed of a net conveyor net are detachably attached to the conveyor chain at the left and right sides (near both ends in the width direction) of the transport direction. If necessary, the vicinity of the left and right ends of the rear part in the transport direction is also detachably attached to the conveyor chain.

The deck module is attached to the conveyor chain by hanging a connecting piece along the inside or outside of the link plate of the conveyor chain at the required place of the deck module.
Line intends to inserting the connecting pin to the connecting piece and link plate.

  The connecting pin used at this time is prevented from coming off from the pin hole. The stopper can be prevented by a method of restricting movement of the connecting pin in the extraction direction with a stopper or the like. Specific examples of the method include the following (1) to (4).

(1) A key is provided on the outer periphery of the connecting pin, and a key groove for passing the key is provided in the pin hole, and the key passing through the key groove is rotated at a position where there is no key groove by relatively rotating the connecting pin and the pin hole. Lock to the link plate or the connecting piece.
(2) A clip portion is formed at the rear of the connecting pin in the insertion direction, and the deck module is sandwiched by the clip portion to add resistance to the return movement of the connecting pin.
(3) A bending return part is formed at the rear part of the connecting pin in the insertion direction, and the bending return part is assembled to the deck module so that movement in the insertion / removal direction of the pin is allowed and urged in the insertion direction by a spring. Hold the insertion state with the force of.
(4) A stopper is formed on the rail that supports the conveyor chain so as to face the rear surface of the connection pin (the end surface at the rear in the insertion direction), and the stopper restricts the movement of the connection pin in the extraction direction.

  In the method of (1), as a more preferable aspect, the key is engaged with a groove formed in a locking partner (link plate or the connecting piece) to maintain the locked state, It is conceivable that the phases of the key grooves respectively formed in the pin holes before and after the insertion direction are shifted so that the phases of the key and the key grooves before and after the connecting pin insertion direction are not aligned at the same time.

  In the case of a conveyor that attaches only the front part of the deck module to the conveyor chain, the rear part of the deck module is supported by the conveyor chain on the forward path, but the rear part of the deck module hangs away from the conveyor chain on the return path, so the deck on the return path It is preferable to provide a moving guide for tilting and guiding the module in a state close to a horizontal posture.

  The forward path referred to here is the side on which transport is performed from the transport start end toward the transport end, and the return path is the side that turns at the transport end and returns toward the transport start end.

  In addition, it is preferable that the conveyor used in an inclined arrangement adopts a deck module in which deck pieces are combined, and is provided with blades and crosspieces that push the conveyed product to several deck pieces in the deck module.

  The conveyor of the present invention can be removed by uncoupling the deck module from the conveyor chain. As for the removal, since the deck module is attached to the conveyor chain as a unit, the number of attachment points can be greatly reduced compared to a conveyor in which a single slat bar is individually attached to the conveyor chain. And speeding up. In particular, when the deck module is attached to the conveyor chain with a connection pin, the connection and the release of the connection are easy, and the effect of simplifying and speeding up the work is great.

  In addition, by removing the deck module that constitutes the transfer surface, it is possible to easily and reliably clean the back side of the transfer surface (the back side of the deck module) and the surface of the peripheral area hidden under the conveyor or on the side. Therefore, the purpose of facilitating cleaning and cleaning without blind spots is achieved.

  In addition, the conveyance conveyor which attaches only the front part of the conveyance direction of a deck module to a conveyor chain has the large reduction effect of the effort of attachment or detachment of a deck module.

  In addition, a transport conveyor in which the front and rear portions of the deck module in the transport direction are detachably attached to the conveyor chain has an advantage that the deck module does not hang down on the return path, although it requires more time to attach and detach.

  Furthermore, a conveyor having a deck module made up of a plurality of deck pieces can produce a more stable conveying surface than a conveyor using a net deck module.

  In the conveyor in which the deck module is attached to the conveyor chain using the connection pins, the attachment of the deck module to the conveyor chain is stabilized by using the methods (1) to (4) to prevent the connection pins from coming off.

  Hereinafter, an embodiment of a conveyor according to the present invention will be described with reference to FIGS. 1-7 has shown the 1st form of the conveyance conveyor of this invention.

  The transport conveyor 1 includes a drive sprocket 2, a driven sprocket 3, a conveyor chain 4 spanning between these sprockets 2, 3, a rail 5 that supports the forward conveyor chain 4, and a deck module that combines a plurality of deck pieces 6. 10. The deck module 10 is detachably attached to the conveyor chain 4 to constitute a transport surface.

  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 4 is placed between each set of the drive sprocket 2 and the driven sprocket 3 in parallel.

  As shown in FIG. 3, the exemplified conveyor chain 4 includes a rolling roller 4a that reduces sliding resistance. Attachments 4c erected vertically are formed at several pitches on the link plate 4b, and the deck modules 10 are attached to the conveyor chain 4 using pin holes 4d provided on the attachments 4c.

  If there is a link where the sprocket teeth do not mesh, the pin hole 4d may be formed directly on the link without the attachment 4c.

  The illustrated deck module 10 employs a deck piece 6 as shown in FIG. 5, that is, a deck piece 6 in which hinge portions 6b and 6c are formed in front and rear of a flat body portion 6a. The hinge portions 6b and 6c are shifted from each other so that one hinge portion enters a recess between the other hinge portions.

  These hinge portions are provided with pin holes 6d penetrating therethrough. One of the pin holes 6d is a hole in which a connecting pin, which will be described later, is loosely fitted, and due to the loose fitting, an extension allowance in the front-rear direction is given to the deck module, which will be described later, and the deck module is turned in the turn portion of the conveyance path It can be bent without any trouble.

  The deck pieces 6 are arranged in a row as shown in FIG. 6, the hinge portions 6b and 6c of the front and rear deck pieces 6 are engaged with each other, and the hinge pins 7 are inserted into the pin holes 6d as shown in FIG. The required number of deck pieces 6 are connected repeatedly. And the connecting piece 11 which becomes an attachment element is provided in the both-ends lower part of the head and tail deck pieces 6, and the deck module 10 shown in figure is formed. The deck module 10 is attached to the conveyor chain 4 and the deck module 10 arranged in one direction constitutes a transport surface. At this time, the deck modules before and after the transport direction are not connected to each other. Accordingly, the frontmost deck piece of each deck module 10 may be omitted from the front hinge portion, and the rearmost deck piece may be omitted from the rear hinge portion.

  The connecting piece 11 is a hanging plate-like component, and is provided at a position along the inner side or the outer side of the link plate 4b. The connecting piece 11 is formed with a pin hole 11a corresponding to the pin hole 4d of the attachment. The deck module 10 is attached to the conveyor chain 4 as shown in FIG. 4 through the connecting pin 12 through the pin hole 11a and the pin hole 4d of the attachment.

  The deck module 10 may be as shown in FIG. The deck module 10 in FIG. 8 cuts a net 8 for a net conveyor into a predetermined length, and attaches a reinforcing material 9 to necessary portions of the net 8 (the front part and the rear part in the conveying direction in the figure). 9 is provided with a connecting piece 11 for attachment having a pin hole 11a.

  The deck module 10 of FIG. 8 can also form a stable transport surface by attaching a total of four locations at the front and rear ends to the conveyor chain 4.

  As shown in FIG. 9, the deck module composed of deck pieces can be provided with standing blades 6 e that push the conveyed product in some deck pieces 6 as necessary. Moreover, in the conveyor for washing | cleaning use, the hole and groove | channel (not shown) for draining can be provided in the deck piece 6. FIG.

  The connecting pin 12 for attaching the deck module 10 to the conveyor chain 4 is prevented from coming off. Specific examples of the retaining are shown in FIGS.

  10, the key 13 is provided on the outer periphery of the connecting pin 12, the key holes 14 through which the key 13 passes are provided in the pin holes 4d and 11a, and the key 13 passing through the key groove 14 is connected. The pin 12 is rotated and locked to the link plate 4b or the connecting piece 11 through which the key 13 has finally passed.

  In this method, one of the pin holes 4d and 11a is provided before and after the connecting pin 12 in the insertion direction, and as shown in FIG. 11, the phase of the key grooves 14 respectively formed in the pin holes before and after the connecting pin insertion direction. It is better to make them different.

  The connecting pin 12 provided with the lever 12a for rotating operation shown in FIG. 12 maintains the same posture in the forward path and the return path because the lever 12a hangs down due to the weight. On the other hand, the pin holes 4d and 11a through the connecting pin 12 rotate 180 degrees when moving from the return path to the forward path or from the return path to the forward path, and this causes the phases of the key 13 and the key groove 14 to coincide with each other. Can be considered.

  In order to solve this problem, as described above, when the phase of the key groove before and after the connecting pin insertion direction is different, the phases of the key 13 and the key groove 14 before and after the connection pin insertion direction are not aligned at the same time. Due to the unexpected rotation of the pin 12, the phase of the key and the key groove coincides and the connecting pin is pulled out at once.

  It is also effective to prevent the connection pin from coming off by engaging the protrusion provided on the connection pin with a groove formed in the locking partner and stopping the rotation of the connection pin at that position. In this method, the key 13 can be used as the convex portion.

  13, the clip portion 12b is formed at the rear portion of the connecting pin 12, and the deck module 10 is sandwiched by the clip portion 12b to add resistance to the return movement of the connecting pin.

  14 is formed with a bent-back portion 12c at the rear portion of the connecting pin 12, and the bent-back portion 12c is slidably incorporated in a sleeve 12d fixed to the upper surface of the deck module 10, and is incorporated in the sleeve 12d. The connecting pin 12 is urged in the insertion direction by the spring 12e. Even in this method, the insertion state of the connecting pin 12 with respect to the pin hole can be maintained.

  In the retaining process of FIG. 15, a stopper 15 a is formed on the rail support portion 15 so as to face the rear surface of the connecting pin 12, and the stopper 15 a restricts the movement of the connecting pin in the extraction direction. The stopper 15a can be produced by forming the rail support portion 15 from L-shaped steel (angle) and using a part of the L-shaped steel. In the conveyor adopting this method, the rail support portion 15 having the stopper 15a is also arranged in the return path, the start end, and the end turn portion, and the rail support portion 15 is cut out at an appropriate position to connect the connecting pin at that position. Reseat.

  FIG. 16 is an example of a transfer conveyor in which only the front portion of the deck module 10 is attached to the conveyor chain 4. In the forward path, the rear part of the deck module 10 is also received and supported by the conveyor chain 4 in the outward path.

  However, in the return path, the support of the rear part in the transport direction of the deck module 10 by the conveyor chain 4 is released. Therefore, a moving guide 16 is provided as an alternative support element that guides the deck module 10 by tilting it to a state close to a horizontal posture on the return path. The movement guide 16 prevents the rear portion of the deck module 10 that is not fixed to the conveyor chain 4 from drooping greatly away from the conveyor chain.

  As described above, the transport conveyor of the present invention is an endless transport surface by continuously connecting a deck module in which a plurality of deck pieces are sequentially hinged and a deck module composed of a net of a predetermined length. Is forming. One deck module is set as a unit, and several portions of the deck module are attached to the conveyor chain, so that the number of attachment portions is greatly reduced as compared with the case where the slat bars are individually attached to the conveyor chain.

  For this reason, the deck module can be removed without wasting time and effort, and by removing the deck module, the blind area can be easily and reliably blinded to the back side of the transport surface and the peripheral area hidden under and on the side of the conveyor. It becomes possible to wash in a state without any water.

  In particular, mounting the deck module using a connecting pin that can be freely inserted into and removed from the pin hole is easy to connect and release, and is advantageous when frequent cleaning is required.
