Description

The present invention relates to a conveyor device, for example, a conveyor device that conveys and supplies a product to a packaging machine body in a horizontal pillow packaging machine and other packaging machines.

As a conveyor device that conveys and supplies the product to the main body of the packaging machine, for example, a finger conveyor that conveys the product at regular intervals is used. This type of conveyor device has a pair of upper plates that form a transport surface on both left and right sides of the fingers that move toward the downstream side, and further covers the upper side edges of the pair of upper plates that are opposite to the fingers. A pair of top plates is arranged so as to project toward the outside of the side edges, and a side wall (also referred to as a conveyor frame) adjacent to the outer side edges of the top plates and extending downward is arranged.

In this type of conveyor device, the side wall and the upper plate are fixed to the machine frame/frame of the device with screws using fixing tools such as bolts and nuts. And, for example, like the supply conveyor of the horizontal bag-making filling machine disclosed in Patent Document 1, the top plate portion may be opened like a double door.

Patent No. 5219052

The device disclosed in Patent Document 1 can clean the inside of the device by utilizing the space that opens the top plate in the double-sided manner and opens the upper plate, but even if the double-sided plate is opened in the double-sided structure, the top surface of the device can be conveyed in the conveying direction. Since the upper plates are fixedly installed on both sides of the fingers along the center along the center, the actual opening area is small.Furthermore, the side plates are fixedly installed on both the left and right sides in the transport direction. By opening the double door, the opening space is narrow and cleaning workability cannot be said to be sufficiently good. Since the space that opens is narrow, maintenance is difficult.

Also, since the side walls are fixedly installed on both the left and right sides in the transport direction, it is difficult to see the inside of the conveyor device.To grasp the inside condition, loosen the fixing tool using a tool such as a bolt and nut and remove it. After that, it is necessary to further remove the side wall, which complicates the work.

Further, the side wall is fixed to a frame member/frame arranged on each side of the generally rectangular parallelepiped or the like at a predetermined portion such as an outer peripheral edge of the side wall with a bolt nut or the like. Therefore, even if the side wall can be removed by removing the bolts and nuts, for example, as described above, the rectangular frame composed of the frame member remains, so the space is not completely open and the remaining frame member is cleaned. May interfere with work or maintenance.

The rotation shafts of the sprocket before and after the endless chain to which the fingers are attached are rotatably supported by the bearing portion linked to the side wall, and are rotated by receiving the rotational force of the drive motor. Therefore, the side wall portion with which the bearing portion is linked cannot be removed, so that the side wall from which the bolts and nuts and the like can be removed is actually a part of the side wall instead of the entire surface. Therefore, the space is not completely open, and there is a risk that it will be an obstacle during cleaning work and maintenance.

The above-mentioned problems are described as being independent of each other, and the present invention does not necessarily have to solve all of the problems described above, as long as at least one problem can be solved. In addition, with regard to the structure for solving this problem, we have the intention to acquire the right by dividing application, amendment, etc.

In order to solve the above-mentioned problems, the conveyor device of the present invention comprises (1) a plurality of fingers that move on the transfer surface along the transfer direction, and transfer surfaces that are arranged on the left and right sides of the moving fingers. A pair of upper plates, a pair of top plates that respectively cover the upper side edges of the pair of upper plates opposite to the fingers and project toward the outside of the side edges; A rotation mechanism, which is arranged outside the top plate and has a pair of side walls arranged so as to cover both left and right side surfaces in the transport direction, and rotates the fingers in a predetermined locus, in a width direction orthogonal to the transport direction. Is supported by a first support mechanism provided at an intermediate point of the above, at least one of the pair of side walls is arranged to be openable and closable, and the internal space is opened with the side walls open.

Since the rotation mechanism that rotates the fingers in a predetermined locus is supported by the first support mechanism provided at the middle point in the width direction, the state in which the fingers and the rotation mechanism are in the predetermined position even if the side wall is opened and closed Can be maintained. Therefore, the side wall can be easily opened and closed. Then, when the side wall in the free state is opened, the inside can be visually recognized from the side of the apparatus, and further, the apparatus/device inside can be touched. Therefore, since it can be visually confirmed, the degree of dirt can be confirmed, the inside of the device becomes hollow and accessible, and workability such as cleaning and maintenance is improved. Further, since the inside of the apparatus can be visually confirmed, the degree of contamination can be confirmed as described above, and the leakage of cleaning can be easily and easily confirmed after the work such as cleaning, so that the hygiene and sanitary properties are improved.

In the embodiment, the rotating mechanism corresponds to, for example, the endless chain 25, the sprocket 24, or the like. The first support mechanism corresponds to, for example, the support plates 20 and 21 and the base plate 23 in the embodiment. In the embodiment, the side wall is opened and closed with the lower end edge as the center of rotation, but it may be bent at an intermediate point so that a part of the side wall is opened and closed. Instead, for example, it may be opened and closed by turning horizontally in a double-door or single-opening manner. However, as in the embodiment, it is preferable to open the entire surface and further open and close with the lower end edge as the center of rotation because a large opening surface can be obtained while suppressing the space for opening and closing.

(2) At least one of the pair of top plates may be detachably attached to the second support mechanism provided at an intermediate point in the width direction orthogonal to the transport direction in a pluggable manner. By doing so, the top is largely opened by removing the top plate, so that the inside of the apparatus can be visually recognized from above and from the side and is in a touching state. 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, if the side wall is opened and the top plate is removed, it can be seen from diagonally above and the working space It is preferable because it becomes wider. In the embodiment, the second support mechanism includes, for example, the receiving plate 57, the moving plate 55, the supporting plate 56, and the like.

(3) At least one of the pair of upper plates may be configured such that a portion forming the transport surface is erected so as to open upward in the erected state. By erecting the portion that constitutes the transport surface, the opening area above the device further increases, so that the confirmation workability, cleaning workability, maintenance workability, and the like are further improved.

(4) At least one of the pair of upper plates may be detachably arranged and detachably provided without using a tool. Removing the top plate may further increase the opening area above the device. Further, since it is configured so that it can be removed without using a tool, workability is improved. In the embodiment without using a tool, a knob screw that can be manually tightened or loosened by an operator is used in the embodiment.However, for example, a spring or other elastic member prevents the lock mechanism from being closed so that the upper plate cannot be removed. Various mechanisms can be used, such as the lock mechanism being opened by urging the elastic member to elastically deform the elastic member so that the upper plate can be removed. However, when the knob screw is used as in the embodiment, the fixing can be reliably performed, the fixing force can be maintained for a long time, and the durability performance is improved, and the attachment/detachment work only needs to be loosened or tightened. It's easy, so it's good.

(5) It is preferable that a guide plate separate from the upper plate is provided at the downstream end of the upper plate, and the downstream portion of the guide plate is inserted and arranged in the bag making machine of the packaging machine. For example, if the conveyor device is used to convey and supply products in a pillow packaging machine, the downstream end of the conveyor device is inserted into the bag making machine, and the upper plate is started or removed, for example. You can do the work you do.

(6) A tool is used as a fixture for fixing a cover member that covers the upstream end portions of the pair of upper plates and the pair of top plates so as to be openable and closable, and that fixes the cover member that covers the upstream end portion. It is good to be able to release the fixation without any. By providing the cover member, it is possible to cover the folded-back portion on the upstream side of the finger that moves along a predetermined trajectory and prevent the user from accidentally touching the finger or the like. Then, by opening the cover member, for example, the work of opening and closing the top plate or the top plate and removing the top plate can be smoothly performed.

Further, since the fixing tool for fixing the cover member in the posture of covering the upstream end portion can be released from the fixing without using a tool, the workability is improved. In the embodiment without using a tool, a knob screw that can be manually tightened or loosened by an operator is used in the embodiment.However, for example, a spring or other elastic member prevents the lock mechanism from being closed so that the upper plate cannot be removed. Various mechanisms can be used, such as the lock mechanism being opened by urging the elastic member to elastically deform the elastic member so that the upper plate can be removed. However, when the knob screw is used as in the embodiment, the fixing can be reliably performed, the fixing force can be maintained for a long time, and the durability performance is improved, and the attachment/detachment work only needs to be loosened or tightened. It's easy, so it's good.

(7) It is preferable that the side wall that is openable and closable is configured to be interlocked in an opened state, and the upper plate and the top plate are configured to maintain a driving posture when the side wall is closed. In this way, since the interlock is applied when the side wall is opened, safety can be ensured. Further, even if the upper plate and the top plate have a configuration in which the posture and position are displaced from the driving posture, the upper plate and the ceiling plate cannot be displaced from the driving posture when the side wall is closed, and the device does not open, which is safe. You can secure it. In the present invention, when the conveyor device is opened, the operation is first performed by opening the side wall.

In the embodiment, the configuration in which the driving posture is maintained in the state where the side wall is closed includes, for example, a cover member that covers the upstream side of the top plate and the upper plate so as to be openable and closable, and when the cover member closes the side wall. It was realized by making the structure that cannot be opened and the structure that the top plate and the upper plate cannot be displaced when the cover member is closed. The present invention is not limited to this, and may have various configurations, such as mechanically connecting the side wall and the top plate so that the top plate cannot move when the side wall is closed. However, the configuration as in the embodiment is preferable because the top plate and the upper plate maintain the driving posture unless the side wall is opened with a simple structure.

(8) When the side wall that is openable and closable is configured to be interlocked in the opened state, and the side wall is closed, the cover member is configured to maintain the posture of covering the upstream end portion. Good. In this way, since the interlock is applied when the side wall is opened, safety can be ensured. Furthermore, even if the cover member is provided with a structure that opens and closes, it is possible to ensure safety because the cover member cannot be displaced from the closed state when the side wall is closed, and the device does not open.

In the embodiment, the configuration in which the driving posture is maintained with the side wall closed is, for example, the head of the knob screw fixing the cover member is located inside the device, and the side wall is closed with respect to the head. It was realized by making the configuration inoperable. The present invention is not limited to this, and can take various configurations, for example, the side wall and the cover member are mechanically connected to each other so that the cover member cannot be opened and closed when the side wall is closed. However, the configuration as in the embodiment is preferable because the cover member maintains the closed state unless the side wall is opened with a simple configuration.

(9) Both of the pair of side walls may be arranged to be openable and closable so that the internal space is opened with the side walls open. In this way, if both side walls are opened together, they are completely opened, and cleaning and maintenance are easier to perform.

According to the present invention, since the side wall is opened and closed, for example, the inside can be visually recognized from the side of the device, and the inside of the device becomes hollow so that the inside device and equipment can be touched, and cleaning, maintenance, etc. Workability is improved.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings. The present invention is not construed as being limited to this, and various changes, modifications, and improvements can be made based on the knowledge of those skilled in the art without departing from the scope of the present invention.

The conveyor device 10 of the present embodiment is arranged, for example, on the upstream side of the body of a packaging machine in a horizontal pillow packaging machine, and supplies products at regular intervals into the bag making machine of the body of the packaging machine. The conveyor device 10 includes a plurality of fingers 11 that move along the carrying direction on the carrying surface, and a pair of upper plates (first upper plate 41, first upper plate 41, which configures the carrying surface arranged on both left and right sides of the moving fingers 11). A second upper plate 42) and a pair of top plates (first top plates 43, 43) arranged so as to cover above the side edges of the pair of upper plates opposite to the fingers 11 and project outward of the side edges. A second top plate 44) and side walls (first side wall 45, second side wall 46) arranged outside the pair of top plates and arranged so as to cover both left and right side surfaces of the conveyor device 10 in the transport direction. Equipped with.

The fingers 11, the upper plate, the top plate, and the side wall are directly or indirectly attached to the pedestal 15 via other members. The pedestal 15 has a downstream leg portion 16 and an upstream leg portion 17 arranged in the front and rear along the transport direction, and a bottom plate 18 supported by the downstream leg portion 16 and the upstream leg portion 17 and arranged in a horizontal plane. Equipped with. The downstream leg portion 16 and the upstream leg portion 17 include a pair of left and right leg plates 16a, 17a and connecting plates 16b, 17b that connect the upper ends of the leg plates 16a, 17a. For example, a slender L-shaped angle 19 is arranged so that the upper left-hand side edges and the upper right-hand side edges of the downstream side leg portion 16 and the upstream side leg portion 17 are bridged, and a pair of left and right L-shaped angle portions 19 are provided. By connecting the bottom plate 18 so as to span it, the downstream leg part 16 and the upstream leg part 17 support the bottom plate 18.

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

The specific arrangement structure connects the lower end of the first side wall 45 and the lower end of the second side wall 46 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 the predetermined angle range with the hinge member 31 as the center of rotation. In the present embodiment, the first side wall 45, the second side wall 46, the upper end is located on the upper side and stands up on a vertical plane, and the operation posture that closes the side surface of the conveyor device 10, and rotates 180 degrees from the operation posture, The upper end is located below, stands upright on a vertical plane, and transits between a standby posture in which the side surface of the conveyor device 10 is opened.

A handle 32 is provided at a predetermined position above the surface of the first side wall 45 and the second side wall 46. The worker holds the handles 32 of the first side wall 45 and the second side wall 46 in a driving posture, for example, and pulls the handles 32 toward the front side to open the side faces, and puts them in a standby posture. Further, at predetermined positions on the back surfaces of the first side wall 45 and the second side wall 46, a metal plate 33 that constitutes a fixing member for holding the first side wall 45 and the second side wall 46 in a driving posture is provided. In a state where the first side wall 45 and the second side wall 46 are in the operating posture, the metal plate 33 faces the magnet 34 arranged at a predetermined position on the pedestal 15 side as described later, and is fixed so as to be detachable by magnetic force. The driving posture is maintained. Further, when the first side wall 45 or the second side wall 46 in the driving posture is held, the handle 32 is held and pulled by the front side with a force larger than the magnetic force of the magnet 34 to open the first side wall 45 or the second side wall 46. Therefore, the conveyor device 10 has a function of controlling so as not to 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 transport direction is provided with a circular opening window portion 45a at a predetermined position on the downstream side.

An L-shaped support plate 20 is arranged at a predetermined position at an intermediate point on the connecting plate 16b of the downstream leg portion 16. The support plate 20 has a horizontally extending portion connected to a predetermined position on the upper surface of the connecting plate 16b, and an upright wall portion 20a extending vertically is arranged so as to be parallel to the transport direction. Similarly, an L-shaped support plate 21 is arranged at a predetermined position at an intermediate point on the connecting plate 17b of the upstream leg portion 17. In this support plate 21, a horizontally extending portion is connected to a predetermined position on the upper surface of the connecting plate 17b, and an upright wall portion 21a extending in the vertical direction is arranged so as to be parallel to the transport direction. The upright wall portion 20a extending in the vertical direction of the support plate 20 and the upright wall portion 21a extending in the vertical direction of the support plate 21 are located on the same plane, and a cross section is formed on one surface of the both upstanding wall portions 20a, 21a. The U-shaped base plate 23 is connected. The base plate 23 is arranged over substantially the entire length of the conveyor device 10.

Bearing portions 22 are provided near the front and rear ends of the base plate 23 in the carrying direction, and the bearing portions 22 rotatably support the rotary shaft 24a of the sprocket 24. Then, the endless chain 25 having a large number of fingers 11 attached at a predetermined pitch is stretched over a plurality of sprockets 24. A power transmission pulley 26 is attached to one end of a rotary shaft 24a of one sprocket 24 arranged downstream, and a drive belt that rotates by receiving a rotation output of a drive motor (not shown) is linked to the power transmission pulley 26. .. As a result, with the rotation of the drive motor, the fingers 11 projecting on the transport surface move toward the downstream side as the sprocket 24 and eventually the endless chain 25 rotate.

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 lower portion of the endless chain 25, which moves along the conveying surface toward the downstream side in the conveying direction, contacts the upper chain guide rail 28, and stably moves straight in a guided state. Further, a lower chain guide rail 30 extending horizontally along the transport direction is attached to the upper surface of the lower bent portion of the base plate 23. The endless chain 25 moving toward the upstream side moves in a state of being in contact with the lower chain guide rail 30, and prevents the downward slack.

The first upper plate 41 is arranged on the right side of the fingers 11 in the conveyance 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 to the other end of the first connecting plate 47 whose one end is fixed at a predetermined position of the base plate 23, for example, via the first hinge member 49. The first upper plate 41 is configured to rotate forward and backward about the first hinge member 49 within an angle range of 90 degrees, for example. The first upper plate 41 transits between a driving posture that is located in a horizontal plane and a standby posture that is rotated 90 degrees from the driving posture and stands up. When the first upper plate 41 is in the driving posture, the first upper plate 41 is located on the transport surface and its tip edge is located near the finger 11. When the first upper plate 41 is in the standby position, the leading edge is separated from the finger 11, the transport surface is opened, and an open space is formed beside the finger 11.

Further, a cutout recess 49b is provided at the center of the tip edge of the movable piece 49a of the first hinge member 49 that contacts the first upper plate 41. The notch recess 49b is dimensioned so that the screw portion of the knob screw 50 mounted on 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 tightened. The movable piece 49a is sandwiched between the portion 50a and the lower surface of the first upper plate 41 with a predetermined pressure. As a result, the first upper plate 41 is fixed to the first hinge member 49 and transitions between the driving posture and the standby posture as the first hinge member 49 is opened and closed.

When the first upper plate 41 is in the operating posture, the knob screw 50 is located on the lower surface side of the first upper plate 41, so that it is hidden inside the conveyor device 10 and cannot be visually recognized or operated from the outside. .. On the other hand, when the first upper plate 41 is in the standby position, the knob screw 50 is exposed to the outside and the head 50a can be operated. Then, when the knob screw 50 is loosened, the fixed state of the first upper plate 41 is released, and the first upper plate 41 can be removed. Therefore, when the first upper plate 41 is in the standby position, a part of the upper surface of the conveyor device 10 is opened, and especially the state near the fingers 11 can be visually recognized, and the work such as cleaning and maintenance is facilitated. Then, when the first upper plate 41 is removed, the openability is further improved, the inside can be easily seen, and the workability such as cleaning and maintenance is further improved.

On the other hand, the second upper plate 42 is connected via the second hinge member 29 to the non-mounting surface side of the base plate 23 of the upright wall portions 20a and 21a extending in the vertical direction of the support plates 20 and 21. The second upper plate 42 is configured to rotate forward and backward about the second hinge member 29 within an angle range of 90 degrees, for example. The second upper plate 42 transits between a driving posture located in a horizontal plane and a standby posture rotated by 90 degrees from the driving posture. When the second upper plate 42 is in the driving posture, the second upper plate 42 is positioned on the transport surface and its tip edge is positioned near the finger 11. When the second upper plate 42 is in the standby position, the leading edge is separated from the finger 11, the transport surface is opened, and an open space is formed next to the finger 11.

Further, a notch recess 29b is provided at the center of the upper edge of the movable piece 29a of the second hinge member 29 that contacts the second upper plate 42. The notch recess 29b is dimensioned so that the threaded portion of the knob screw 38 mounted on the lower surface side of the second upper plate 42 is inserted. When the knob screw 38 is tightened, the head of the knob screw 38 is tightened. The movable piece 29a is sandwiched between the portion 38a and the lower surface of the second upper plate 42 with a predetermined pressure. As a result, the second upper plate 42 is fixed to the second hinge member 29, and transitions between the driving posture and the standby posture as the second hinge member 29 is opened and closed.

When the second upper plate 42 is in the operating posture, the knob screw 38 is located on the lower surface side of the second upper plate 42 and therefore hidden inside the conveyor device 10 so that it cannot be visually recognized or operated from the outside. .. On the other hand, when the second upper plate 42 is in the standby posture, the knob screw 38 is exposed to the outside, and the head portion 38a can be operated. Then, when the knob screw 38 is loosened, the fixed state of the second upper plate 42 is released, and the second upper plate 42 can be removed. 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 especially the state near the fingers 11 can be visually recognized, and the work such as cleaning and maintenance is facilitated. Then, when the second upper plate 42 is removed, the openability is further improved and the inside can be easily seen, and the workability such as cleaning and maintenance is further improved. The above-described opening/closing/removing work of the first upper plate 41 and the opening/closing/removing work of the second upper plate 42 can be independently performed.

The second connecting plate 51 is attached to the other end of the first connecting plate 47 so as to extend toward the first side wall 45. The magnet 34 is attached to the tip of the second connecting plate 51. The positions of the respective members 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 connection plate 51 in the operating posture in which the first side wall 45 is closed.

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 the magnet 34 is attached to the tip of the third connecting plate 52. Attach. The positions of the respective members are set so that the metal plate 33 provided on the second side wall 46 faces the magnet 34 attached to the tip of the third connecting plate 52 in the operating posture in which the second side wall 46 is closed.

The first top plate 43 covers the upper side of the side edge of the first upper plate 41 opposite to the fingers 11, and is arranged so as to reach the vicinity of the upper end of the first side wall 45. Similarly, the second top plate 44 is arranged so as to cover the upper side edge of the second upper plate 42 opposite to the finger 11 and reach the vicinity of the upper end of the second side wall 46. The first top plate 43 and the second top plate 44 are both insertable and detachably attached. Specifically, for example, the rotary shafts 54 are rotatably mounted at predetermined positions on the upstream side and the downstream side of the base plate 23 via bearing portions. The rotary shaft 54 has reverse screw portions on both sides of the bearing portion, and the moving plates 55 are attached to the reverse screw portions, respectively. Then, a support plate 56 extending upward is attached to the moving plate 55, and a strip plate-shaped receiving plate 57 is connected to the upper end of the support plate 56. The receiving plate 57 is arranged so as to extend in a direction orthogonal to the transport direction, and two through holes 57a and 57b are arranged along the orthogonal direction. One end of the rotary shaft 54 provided on the downstream side reaches the vicinity of the first side wall 45, and the operation handle 67 is connected to the one end. Further, the front and rear rotation shafts are linked to each other, and when the operation handle 67 is normally or reversely rotated, the front and rear rotation shafts are synchronously or normally rotated. Therefore, when the operation handle 67 is rotated in the forward or reverse direction, the front and rear rotary shafts 54, and thus the pair of left and right moving plates 55, the receiving plate 57, etc. mounted on the same rotary shaft 54 approach or separate from each other. ..

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

On the other hand, the first top plate 43 and the second top plate 44 have, for example, a shape having a peripheral wall extending downward from the outer peripheral edge of a flat plate-shaped main body, and positioning protrusions 43a and 44a are provided at predetermined positions on the lower surface of the main body. .. When mounting the first top plate 43, the positioning protrusions 43a arranged at predetermined front and rear positions on the lower surface are inserted into the through holes 57a provided on the finger 11 side of the receiving plate 57 from above to position and mount. To do. Similarly, when the second top plate 44 is mounted, the positioning protrusions 44a arranged at predetermined front and rear positions on the lower surface are inserted into the through holes 57a provided on the finger 11 side of the receiving plate 57 from above to position and mount the second top plate 44.
