Description

The present invention relates to a conveyor device, and for example, to a conveyor device for conveying and supplying products to a packaging machine body in a horizontal pillow packaging machine or other packaging machine.

The conveyor device that conveys and supplies the products to the packaging machine main body is, for example, a finger conveyor that conveys the products at regular intervals. This type of conveyor device has a pair of upper plates that form the conveying surface on both sides of the fingers that move downstream, and further covers the upper side edges of the pair of upper plates on the opposite side of the fingers. A layout is adopted in which a pair of top plates are arranged so as to protrude toward the outside of the side edges, and a side wall (also called a conveyor frame) is arranged adjacent to the outer side edge of the top plates and extends downward.

In this type of conveyor device, the side walls and the top plate are screwed and fixed to the machine frame of the device using fixing devices such as bolts and nuts and screws. For example, as in the supply conveyor of a horizontal bag-forming-filling machine disclosed in Patent Document 1, the top plate portion is opened, for example, in the form of double doors.

Patent No. 5219052

Although the device disclosed in Patent Document 1 can clean the inside of the device by using the space opened upward by opening the top plate in double doors, there is no space on the top surface of the device in the transport direction even if the top plate is open in double doors. Since the top plate is fixedly installed on both sides of the finger in the center along the top plate, the actual opening area is small. The space opened by double-dooring is narrow, and it cannot be said that cleaning efficiency is sufficiently improved. Since the opening space is narrow, maintenance is difficult.

In addition, since side walls are fixed on both the left and right sides in the conveyor direction, it is difficult to see the inside of the conveyor device, and in order to understand the internal situation, loosen the fixings and remove them using tools such as bolts and nuts. After that, it is necessary to remove the side wall, which makes the work complicated.

Further, the side wall is fixed at a predetermined portion such as the outer peripheral edge of the side wall to a frame member/frame arranged on each side of the substantially rectangular parallelepiped with bolts and nuts. Therefore, as mentioned above, even if it is possible to remove bolts and nuts and remove the side wall, the rectangular framework made up of the frame members will remain, so the space will not be completely open, and the remaining frame members will not be able to be cleaned. It may get in the way during work or maintenance.

The rotating shafts of the sprockets before and after the endless chain to which the fingers are attached are rotatably supported by bearings connected to the side wall, and are configured to rotate in response to the rotational force of the drive motor. Therefore, since the part of the side wall to which the bearing part is linked cannot be removed, the part of the side wall that can be removed by removing bolts and nuts is actually a part of the side wall, not the entire surface. Therefore, the space is not completely open and may become a hindrance during cleaning work or maintenance.

The above-mentioned problems are described as independent ones, and the present invention does not necessarily need to be able to solve all of the described problems, but only needs to be able to solve at least one problem. We also have the intention to acquire rights to a structure to solve this problem through divisional applications, amendments, etc.

In order to solve the above-mentioned problems, the conveyor device of the present invention includes a plurality of fingers that move on a conveyance surface in the conveyance direction, and a pair of fingers that constitute the conveyance surface and are arranged on both left and right sides of the moving fingers. a top plate; a pair of top plates disposed to respectively cover above the side edges of the pair of top plates opposite to the fingers and protrude toward the outside of the side edges; and the pair of top plates. A rotation mechanism that rotates the finger in a predetermined locus is provided with a pair of side walls disposed on the outside of the frame and disposed so as to cover both the left and right sides in the conveyance direction, and a rotation mechanism that rotates the finger in a predetermined trajectory is installed at the center of the width direction perpendicular to the conveyance direction. The finger is supported by a first support mechanism provided at a point, and at least one of the pair of side walls is arranged to be freely openable and closable, and the internal space is opened when the side wall is open. The first support mechanism has an endless chain attached at a predetermined pitch and a sprocket that spans the endless chain, and the first support mechanism is arranged along the conveyance direction and supports a part of the endless chain that moves along the conveyance direction. The sprocket is configured to be rotatably supported by a bearing.

Since the rotation mechanism that rotates the finger in a predetermined trajectory is supported by the first support mechanism provided at the midpoint in the width direction, the finger and its rotation mechanism remain in the predetermined position even when the side wall is opened or closed. can be maintained. Therefore, the side wall can be easily opened and closed. When the free side wall is opened, the inside of the device can be viewed from the side, and the devices and equipment inside can be touched. Therefore, since it is visible, the degree of dirt can be confirmed, and the interior of the device is hollow and accessible, improving workability for cleaning and maintenance. In addition, since the inside of the device can be visually checked, it is possible to check the degree of dirt as described above, and it is also possible to easily check for leaks in cleaning after cleaning, thereby improving hygiene.

In the embodiment, the rotation mechanism corresponds to, for example, the endless chain 25 or the sprocket 24. In the embodiment, the first support mechanism corresponds to, for example, the support plates 20 and 21, the base plate 23, and the like. In the embodiment, the side wall opens and closes entirely around the lower edge as the center of rotation, but it may be bent at an intermediate point so that a part of the side wall opens and closes. Instead, it may be opened and closed by pivoting in the horizontal direction, for example, with double doors or single doors. However, as in the embodiment, it is preferable to open the entire surface and further open and close the lower end edge as the center of rotation, since this allows the opening surface to be made larger while reducing the space for opening and closing.

At least one of the pair of top plates may be removably inserted into a second support mechanism provided at a midpoint in a width direction perpendicular to the conveyance direction in a region where the top plate is arranged. In this way, the top is largely opened by removing the top plate, so that the inside of the device can be seen and touched from above and from the side. Therefore, confirmation workability, cleaning workability, maintenance workability, etc. are further improved. For example, if a frame is not provided at the boundary between the side wall that can be opened and closed and the top plate that can be removed as in the embodiment, when the side wall is opened and the top plate is removed, it can be seen from diagonally above and the work space is This is preferable because it becomes wider. In the embodiment, the second support mechanism includes, for example, a receiving plate 57, a moving plate 55, a supporting plate 56, and the like.

It is preferable that at least one of the pair of upper plates is provided so that a portion constituting the conveyance surface can stand up, and is configured to open upward in the upright state. By raising the portion constituting the conveyance surface, the upper opening area of the device is further increased, so that confirmation workability, cleaning workability, maintenance workability, etc. are further improved.

It is preferable that at least one of the pair of upper plates is removably arranged and provided so as to be removable without using a tool. Removing the top plate is good because it further increases the opening area above the device. Furthermore, the structure is such that it can be removed without using any tools, which improves work efficiency. In the embodiment, the tool-free configuration uses a knob screw that can be tightened or loosened by an operator by hand. Various mechanisms can be used, such as one in which a locking mechanism is opened by biasing the elastic member to elastically deform the elastic member, and the upper plate is made detachable. However, if knob screws are used as in the embodiment, the fixation can be ensured, and the fixing force can be maintained for a long period of time, improving durability, and attachment/detachment can be done by simply loosening or tightening the knob screws. , which is good because it is easy.

A guide plate separate from the upper plate may be provided at the downstream end of the upper plate , and the downstream portion of the guide plate may be inserted into a bag making device of a packaging machine. For example, when a conveyor device is used to convey and supply products in a pillow packaging machine, the downstream end of the conveyor device can be inserted into a bag making machine and the upper plate can be raised or removed. be able to perform tasks.

A fixing device for attaching a cover member covering upstream end portions of the pair of upper plates and the pair of top plates so as to be openable and closable, and fixing the cover member in a position covering the upstream end portions without using a tool. It is preferable to use something that can be unfixed. By providing the cover member, it is possible to cover the folded portion on the upstream side of the finger that moves along a predetermined trajectory, thereby preventing the user from accidentally touching the finger or the like. By opening this cover member, for example, operations such as opening, closing, or removing the top plate or upper plate can be performed smoothly.

Furthermore, since the fixing device for fixing the cover member in the position covering the upstream end portion can be released without using a tool, work efficiency is improved. In the embodiment, the tool-free configuration uses a knob screw that can be tightened or loosened by an operator by hand. Various mechanisms can be used, such as one in which a locking mechanism is opened by biasing the elastic member to elastically deform the elastic member, and the upper plate is made detachable. However, if knob screws are used as in the embodiment, the fixation can be ensured, and the fixing force can be maintained for a long period of time, improving durability, and attachment/detachment can be done by simply loosening or tightening the knob screws. , which is good because it is easy.

In order to solve the above-mentioned problems, the conveyor device of the present invention includes (1) a plurality of fingers that move on a conveying surface in the conveying direction, and a conveying surface that is arranged on both left and right sides of the moving fingers. a pair of upper plates; a pair of top plates disposed to respectively cover the upper side edges of the pair of upper plates opposite to the fingers and protrude toward the outside of the side edges; A rotation mechanism that rotates the fingers in a predetermined trajectory is provided with a pair of side walls disposed on the outside of the plate and arranged to cover both the left and right sides in the conveyance direction, and a rotation mechanism that rotates the fingers in a predetermined trajectory. The side wall is supported by a first support mechanism provided at an intermediate point, and at least one of the pair of side walls is arranged to be freely openable and closable, and the side wall is configured such that an internal space is opened when the side wall is open. It is preferable that the interlock is applied when the side wall is open, and the upper plate and the top plate maintain the driving position when the side wall is closed. In this way, when the side wall is opened, an interlock will be applied, ensuring safety. Furthermore, even if the upper plate or top plate is configured to be displaced from the operating position, when the side walls are closed, the upper plate or top plate cannot be displaced from the operating position, and the device will not open, resulting in safety concerns. Good because it can be secured. In the present invention, when opening the conveyor device, the configuration is such that the side wall is first opened.

In the embodiment, a configuration in which the driving position is maintained with the side wall closed is such that, for example, a cover member that covers the top plate and the upstream side of the upper plate is provided so as to be openable and closable, and furthermore, when the side wall is closed, the cover member is provided so as to be openable and closable. This was achieved by creating a structure that cannot be opened, and a structure in which the top plate and top plate cannot be displaced when the cover member is closed. The present invention is not limited to this, and can take various configurations, such as, for example, when the side wall is closed, the side wall and the top plate are mechanically connected to prevent the top plate from moving. However, the configuration as in the embodiment is preferable because it is a simple configuration and the top plate and the upper plate maintain the driving position unless the side walls are opened.

With such a configuration, when the side wall is closed, it is preferable that the cover member maintains a posture covering the upstream end portion. In this way, when the side wall is opened, an interlock will be applied, ensuring safety. Furthermore, even if the cover member is configured to open and close, the cover member cannot be displaced from the closed state when the side wall is closed, and the device will not open, so safety can be ensured.

In the embodiment, the configuration in which the driving position is maintained with the side wall closed is such that, for example, the head of the knob screw that fixes the cover member is located inside the device, and when the side wall is closed, the head of the knob screw that fixes the cover member is located inside the device, and when the side wall is closed, This was achieved by creating a configuration that made it impossible to operate. The present invention is not limited to this, and can take various configurations, such as, for example, when the side wall is closed, the side wall and the cover member are mechanically connected to each other so that the cover member cannot be opened or closed. However, the configuration as in the embodiment is preferable because it is a simple configuration and the cover member remains closed unless the side wall is opened.

(3) Both of the pair of side walls may be arranged so as to be freely openable and closable, and the internal space may be opened when the side walls are open. In this way, when both side walls are opened, it is completely opened, making cleaning and maintenance easier.

For example, an elongated L-shaped angle 19 is arranged so as to span the upper left edges and the upper right edges of the downstream leg 16 and the upstream leg 17, and the pair of L-shaped angles 19 arranged on the left and right are By connecting the bottom plate 18 in a spanning manner, the downstream leg portion 16 and the upstream leg portion 17 support the bottom plate 18.

A first side wall 45 is arranged on the right edge of the upper surface of the pedestal 15 in the conveyance direction, and a second side wall 46 is arranged on the left edge. In this embodiment, the first side wall 45 is located in front of the conveyor device 10 installed in an operable state, and the second side wall 46 is located in the back side of the conveyor device 10.

Specifically, the lower end of the first side wall 45 and the lower end of the second side wall 46 are connected to the L-shaped angle 19 via the hinge member 31. As a result, the pair of left and right first side walls 45 and second side walls 46 rotate forward and backward independently of each other within a predetermined angular range about the hinge member 31 as the center of rotation. In this embodiment, the first side wall 45 and the second side wall 46 have an operating posture in which the upper ends thereof are located upward and stand up on a vertical plane and close the side surface of the conveyor device 10, and rotate 180 degrees from the operating posture, The conveyor apparatus 10 transitions between a standby position in which the upper end is positioned downward and stands up on a vertical plane, and the side surface of the conveyor apparatus 10 is opened.

A handle 32 is provided at a predetermined position above the surfaces of the first side wall 45 and the second side wall 46 . For example, the worker holds the handles 32 of the first side wall 45 and the second side wall 46 in the driving position and pulls them toward the user to open the sides and take the standby position. Moreover, a metal plate 33 that constitutes a fixing member for holding the first side wall 45 and the second side wall 46 in the driving position is provided at a predetermined position on the back surface of the first side wall 45 and the second side wall 46. When the first side wall 45 and the second side wall 46 are in the operating position, this metal plate 33 faces a magnet 34 placed at a predetermined position on the pedestal 15 side, as will be described later, and is removably fixed by magnetic force. The driving posture is maintained. Furthermore, when the first side wall 45 or the second side wall 46 in the driving position is opened by holding the handle 32 and pulling it toward you with a force greater than the magnetic force of the magnet 34, the interlock is activated. The conveyor device 10 has a function to control the conveyor device 10 so that it does not operate. The first side wall 45 and the second side wall 46 are configured to open and close independently. Further, the first side wall 45 located on the front side of the conveyor device 10 on the right side in the conveyance direction is provided with a circular opening window 45a at a predetermined position on the downstream side.

An L-shaped support plate 20 is disposed at a predetermined intermediate position on the connecting plate 16b of the downstream leg 16. This support plate 20 has a horizontally extending portion connected to a predetermined position on the upper surface of the connecting plate 16b, and a vertically extending standing wall portion 20a arranged parallel to the conveying direction. Similarly, an L-shaped support plate 21 is disposed at a predetermined intermediate position on the connection plate 17b of the upstream leg 17. This support plate 21 has its horizontally extending portion connected to a predetermined position on the upper surface of the connecting plate 17b, and its vertically extending upright wall portion 21a is arranged parallel to the conveying direction. The vertically extending standing wall 20a of the support plate 20 and the vertically extending standing wall 21a of the supporting plate 21 are located on the same plane, and one side of the standing walls 20a, 21a has a cross section. The U-shaped base plates 23 are connected. This base plate 23 is arranged over almost the entire length of the conveyor device 10.

Bearing portions 22 are provided near both front and rear ends of the base plate 23 along the conveyance direction, and the rotation shaft 24a of the sprocket 24 is rotatably supported by the bearing portion 22. Then, an endless chain 25 to which a large number of fingers 11 are attached at a predetermined pitch is passed around a plurality of sprockets 24. A power transmission pulley 26 is attached to one end of the rotating shaft 24a of one of the sprockets 24 disposed downstream, and a drive belt that rotates in response to the rotational output of a drive motor (not shown) is connected to the power transmission pulley 26. . As a result, as the drive motor rotates, the sprocket 24 and, in turn, the endless chain 25 rotate, and the fingers 11 protruding above the conveying surface move toward the downstream side.

An upper chain guide rail 28 extending horizontally along the transport direction is attached to the upper surface of the upper bent portion of the base plate 23 having a U-shaped cross section. The endless chain 25, which moves along the conveyance surface toward the downstream side in the conveyance direction, has its lower portion in contact with the upper chain guide rail 28, and stably moves straight while being guided. Further, a lower chain guide rail 30 is attached to the upper surface of the lower bent portion of the base plate 23, which extends horizontally along the conveyance direction. An endless chain 25 moving toward the upstream side moves in a state of contacting a lower chain guide rail 30, and is prevented from sagging downward.

The first upper plate 41 is arranged on the right side of the finger 11 in the conveying direction, and the second upper plate 42 is arranged on the left side. The connection structure of the first upper plate 41 and the second upper plate 42 to the pedestal 15 is as follows.

The first upper plate 41 is connected, for example, to the other end of a first connecting plate 47, one end of which is fixed to a predetermined position of the base plate 23, via a first hinge member 49. The first upper plate 41 is configured to rotate forward and backward around the first hinge member 49 within an angular range of, for example, 90 degrees. The first upper plate 41 transitions between a driving position located in a horizontal plane and a standby position rotated 90 degrees from the driving position and standing up. When the first upper plate 41 is in the operating position, the first upper plate 41 is located on the conveying surface, and its leading edge is located near the fingers 11. When the first upper plate 41 is in the standby position, the leading edge is separated from the fingers 11, the conveyance surface is opened, and an open space is formed beside the fingers 11.

Further, the first hinge member 49 is provided with a notch recess 49b at the center of the tip edge of the movable piece 49a that contacts the first upper plate 41. This notch recess 49b is sized so that the threaded portion of the knob screw 50 attached to the lower surface side of the first upper plate 41 is inserted, and when the knob screw 50 is tightened, the head of the knob screw 50 is inserted.

When the first upper plate 41 is removed, the openness becomes even better and the interior becomes easier to see, and workability such as cleaning and maintenance is further improved.

On the other hand, a second upper plate 42 is connected via a second hinge member 29 to the side of the vertically extending upright wall portions 20a, 21a of the support plates 20, 21 on which the base plate 23 is not attached. The second upper plate 42 is configured to rotate forward and backward around the second hinge member 29 within an angular range of, for example, 90 degrees. The second upper plate 42 transitions between a driving position located in a horizontal plane and a standby position rotated 90 degrees from the driving position. When the second upper plate 42 is in the operating position, the second upper plate 42 is located on the conveying surface, and its leading edge is located near the fingers 11. When the second upper plate 42 is in the standby position, the leading edge is separated from the fingers 11, the conveyance surface is opened, and an open space is formed beside the fingers 11.

Further, the second hinge member 29 is provided with a notch recess 29b at the center of the upper edge of the movable piece 29a that contacts the second upper plate 42. This notch recess 29b is dimensioned so that the threaded portion of the knob screw 38 attached to the lower surface side of the second upper plate 42 is inserted, and when the knob screw 38 is tightened, the head of the knob screw 38 is inserted. The movable piece 29a is sandwiched between the portion 38a and the lower surface of the second upper plate 42 with a predetermined pressure. Thereby, the second upper plate 42 is fixed to the second hinge member 29, and as the second hinge member 29 opens and closes, it transitions between the operating position and the standby position.

When the second upper plate 42 is in the operating position, the knob screw 38 is located on the lower surface side of the second upper plate 42, so it is hidden inside the conveyor device 10 and cannot be seen or operated from the outside. . On the other hand, when the second upper plate 42 is in the standby position, the knob screw 38 is exposed to the outside and the head 38a can be operated. Then, when the knob screw 38 is loosened, the fixed state of the second upper plate 42 is released and it becomes possible to remove it. Therefore, when the second upper plate 42 is in the standby position, a part of the upper surface of the conveyor device 10 is opened, and the area around the fingers 11 in particular can be visually checked, and work such as cleaning and maintenance can be easily performed. When the second upper plate 42 is removed, the openness becomes even better and the inside becomes easier to see, and workability such as cleaning and maintenance is further improved. The above-described opening/closing and removing operations of the first upper plate 41 and the opening/closing and removing operations of the second upper plate 42 are configured so that they can be performed independently.

A second connection plate 51 is attached to the other end of the first connection plate 47 so as to extend toward the first side wall 45 side. A magnet 34 is attached to the tip of the second connection plate 51. The positions of each member are set so that the metal plate 33 provided on the first side wall 45 faces the magnet 34 attached to the tip of the second connecting plate 51 in the driving position with the first side wall 45 closed.

Further, a third connecting plate 52 is connected to a predetermined position on the surface of the base plate 23 facing the second side wall 46 so as to extend toward the second side wall 46, and a magnet 34 is attached to the tip of the third connecting plate 52.

Similarly, the second top plate 44 is arranged to cover the upper side edge of the second top plate 42 opposite to the fingers 11 and to reach near the upper end of the second side wall 46 . The first top plate 43 and the second top plate 44 are both plug-in type and detachably attached. Specifically, for example, the rotating shaft 54 is rotatably attached to predetermined positions on the upstream and downstream sides of the base plate 23 via bearings. This rotating shaft 54 has reverse threaded portions on both sides of the bearing portion, and a moving plate 55 is attached to each of the reverse threaded portions. A supporting plate 56 extending upward is attached to the moving plate 55, and a band-shaped receiving plate 57 is connected to the upper end of the supporting plate 56. The receiving plate 57 is arranged to extend in a direction perpendicular to the conveying direction, and two through holes 57a and 57b are arranged along the orthogonal direction. One end of the rotating shaft 54 provided on the downstream side reaches near the first side wall 45, and an operating handle 67 is connected to the one end. Further, the front and rear rotating shafts are linked, and when the operating handle 67 is rotated in the forward and reverse directions, the front and rear rotating shafts are synchronously rotated in the forward and reverse directions. Therefore, when the operating handle 67 is rotated forward or backward, the front and rear rotating shafts 54, as well as the pair of left and right moving plates 55, receiving plates 57, etc. attached to the same rotating shaft 54, move closer to each other or move away from each other. .

Further, the operating handle 67 protrudes to the outside through an opening window 45a provided in the first side wall 45, and can be rotated in forward and reverse directions in a driving position with the first side wall 45 closed. Further, when the first side wall 45 is opened and closed, the opening window portion 45a passes through the fixedly installed operating handle 67, thereby allowing the opening/closing operation without interfering with the operating handle 67.

On the other hand, the first top plate 43 and the second top plate 44 have a shape including a peripheral wall extending downward from the outer peripheral edge of a flat body, for example, and are provided with positioning protrusions 43a and 44a at predetermined positions on the bottom surface of the main body. . When installing the first top plate 43, the positioning protrusions 43a arranged at predetermined positions on the front and back of the lower surface are inserted from above into the through holes 57a provided on the finger 11 side of the receiving plate 57, thereby positioning and installing the first top plate 43. do. Similarly, when installing the second top plate 44, positioning protrusions 44a placed at predetermined positions in the front and back of the lower surface are inserted from above into the through holes 57a provided on the finger 11 side of the receiving plate 57, thereby positioning and installing the second top plate 44. do. When the positioning protrusions 43a, 44a are fully inserted into the through holes 57a, the first top plate 43 and the second top plate 44 are supported with their lower surfaces in contact with the receiving plate 57.
