Description

  The present invention relates to a conveying device, and more particularly to a conveying device that conveys a moving conveying member while contacting the article.

The article placed on the bottom part (article placement surface) of the weighing table composed of a flat plate member is placed above the weighing table, and the pusher member is formed with a comb member hanging downward toward the weighing table. A conveyance device that pushes and conveys the toner has been proposed (for example, see Patent Document 1).
The weighing table made of the above flat plate member covers the entire surface with a single plate, so that dust or the like does not fall into the weighing unit located below the weighing table, so that it is easy to clean. Have.

  However, since the method of pressing and conveying the article by the pusher member is used, the lower end part of the comb member of the pusher member and the bottom part (article placing surface) of the weighing table made of a flat plate member are not in contact with each other due to the structure. Thus, a constant interval is provided.

On the other hand, fresh food items (articles) such as meat and fish placed on the weighing table are stored in a tray having side walls rising from the four sides of the rectangular bottom, and the upper surface of the article stored in the tray is It is common to cover and package with film etc., but recently, the price of trays has risen due to soaring raw material costs. For this reason, by making the tray with side walls thinner and lighter, Attempts have been made to reduce the cost of raw materials used.
In addition to cost reduction, in order to reduce the volume when the used tray is discarded, a plate-like tray without the side wall or a side wall having a lower height than the conventional side wall is provided even if the side wall is present. A system in which articles are placed on a tray and packaged with a film or the like is employed.

  When an unwrapped article is placed on such a tray and is to be transported by the transporting device, the pusher member's comb member does not contact the side wall of the tray, but directly presses the product, and as a result, There is a problem in that the position of the article is shifted or the article rolls off from the tray, and the article is not conveyed correctly.

  Furthermore, for example, when a thin sliced ham or the like is transported on the plate-shaped tray, when the height of the article is smaller than the interval (gap) between the bottom surface of the weighing table and the tip of the comb member of the pusher member, There is also a problem that the comb member of the pusher member moves without contacting the article and the article is not conveyed.

Japanese Patent No. 3574385

  The present invention has been made in view of the above-described problems of the prior art, and the object of the present invention is a container having a low height (a flat tray, a tray having a slight side wall, etc.). Provided is a conveying device that can reliably convey.

In order to achieve the above object, the transport apparatus of the present invention transports an article to a predetermined position by a transport member that moves while supporting the article placed on the placement surface of the dish-like article placement portion. In the apparatus, the article placement portion is characterized in that a groove portion is continuously formed on the placement surface in the conveyance direction, and a conveyance claw portion located in the groove portion is formed to protrude on the conveyance member. (Claim 1).
The groove portion formed on the placement surface of the article placement portion is formed by injection molding such that the entire material thickness of the article placement portion is substantially uniform including the groove portion, or the groove portion portion is determined from the material thickness. Any method such as excavation and formation may be used.

  According to the above means, since the conveyance claw portion of the conveyance member is positioned and moved in the groove portion formed on the placement surface of the article placement portion, the article placed on the placement surface of the article placement portion is Even in the case of a flat thin tray, the tray is reliably pushed and conveyed by the conveyance claw portion protruding downward from the placement surface. Further, since the groove portion covers the range of the article placement portion with a bottomed groove, dust or the like does not fall downward at least within the range of the article placement portion. Even when dust or the like accumulates on the article placement portion, it can be easily cleaned.

  The number (number) of grooves formed on the mounting surface, the formation position, the groove shape, and the like are arbitrary, but the grooves may be formed in a specific range in the width direction of the mounting surface (Claim 2). . That is, the groove portion is arranged and formed in a specific range in the width direction of the article placement portion. For example, when the width direction of the article placement portion is divided into three regions, that is, the left side, the right side, and the center, the specific range includes a groove portion arranged and formed in any one of the three regions. The specific range is determined by the working mode of an apparatus (for example, a packaging apparatus or the like) connected and arranged on the downstream side of the transport apparatus.

According to the above means, since the grooves are concentrated and arranged in a specific range in the width direction of the article placement section, the operator can fix the position when placing the article on the article placement section. it can. That is, the article can be conveyed to the required position by matching the specific range in which the groove portion is arranged with the position required by the apparatus connected to the subsequent stage (downstream side of the conveying apparatus). For example, by arranging and forming the groove portion in a substantially central portion in the width direction of the article placement portion, the convex portion (formed by the groove portions) for supporting the article is substantially in the middle of the conveyance device (perpendicular to the conveyance direction). They will be arranged in the center of the width direction. For example, when a packaging device is provided at the subsequent stage of the transport device, the article is transported to the approximate center of the packaging area, so that the article can be evenly packaged at the approximate center of the packaging film. . That is, since the convex portion is located at a substantially central position, the placement position of the article can be shown to the operator.
In addition, a label sticking device is provided at the rear stage of the transport device, and when it is desired to stick a label at a certain position of an article to be transported, there is a convex portion at the center position or the left or right end portion as described above. An article is placed at that position, and a label can be attached at a predetermined position.

  Furthermore, although the said conveyance nail | claw part may be integrally formed with respect to the conveyance member, this conveyance claw part may be formed detachably with respect to a conveyance member. The transport claw portion is arranged so as to intersect with the transport member along the width direction of the article mounting portion at a substantially right angle, but is detachable from a root portion that intersects with the transport member at a substantially right angle, or Any may be used, such as making the tip portion inserted into the groove portion detachable.

  According to the above means, it is possible to arrange the conveyance claw portion that contacts the side surface of the article (the rear side surface with respect to the conveyance direction) and pushes the article only in the necessary range of the conveyance member. Thereby, the placement position of the article in the width direction of the article placement section can be specified (positioned) at the position of the transport claw section.

  A guide that further conveys the article further downstream at a downstream position adjacent to the article placement section, and that guides the conveyance claw of the conveyance member upward from the groove immediately before the conveyor; It is good also as a structure provided with the means (Claim 4).

  According to the above means, the conveyance claw portion of the conveyance member is guided and moved in a state of being fitted into the groove portion of the article placement portion, and on the downstream side of the article placement portion, the placement surface of the article placement portion and When there is a conveyor portion having substantially the same level (height), the transport member is prevented from moving. However, the guiding means for guiding and moving the conveying member is configured to guide the conveying member by separating the conveying claw portion upward from the groove portion on the downstream side in the moving direction on the article placement portion, thereby conveying the conveying member. The member can be continuously moved, and the article on the article placement unit can be reliably transferred onto the conveyor unit disposed on the downstream side.

  Furthermore, the said conveying apparatus may be arrange | positioned as a conveying apparatus which carries in in the packaging apparatus which packages articles | goods with a film, and may comprise a packaging apparatus (Claim 5).

  According to the above means, even a thin tray is surely carried into the packaging device, so that it can be stably packaged.

According to the transport apparatus of the present invention, the transport claw portion moves along the groove portion formed on the mounting surface according to the configuration described in claim 1, so that the transport claw portion contacts the side edge of the tray even in a thin tray. Thus, the tray can be reliably conveyed. And since the groove part covers the range of the article placement part with a bottomed groove, dust or the like does not fall down at least within the range of the article placement part. Even if it accumulates, it can be easily cleaned.
According to the second aspect of the present invention, the position when the article is placed on the article placement section can be shown to the operator. That is, the article can be conveyed to the required position by matching the specific range in which the groove portion is arranged with the position required by the apparatus connected to the subsequent stage (downstream side of the conveying apparatus). For example, by arranging and forming the groove portion in a substantially central portion in the width direction of the article placement portion, the convex portion (formed by the groove portions) for supporting the article is substantially in the middle of the conveyance device (perpendicular to the conveyance direction). They will be arranged in the center of the width direction. For example, when a packaging device is provided at the subsequent stage of the transport device, the article is transported to the approximate center of the packaging area, so that the article can be evenly packaged at the approximate center of the packaging film. .
In addition, a label sticking device is provided at the rear stage of the transport device, and when it is desired to stick a label at a certain position of an article to be transported, there is a convex portion at the center position or the left or right end portion as described above. An article is placed at that position, and a label can be attached at a predetermined position.

Furthermore, according to the configuration of the third aspect, it is possible to arrange the conveyance claw portion that abuts against the side surface (the rear side surface with respect to the conveyance direction) of the article and pushes the article only in the necessary range of the conveyance member. Thereby, the placement position of the article in the width direction of the article placement section can be specified (positioned) at the position of the transport claw section.
According to the fourth aspect of the present invention, the conveying member can be continuously moved, and the article on the article placing portion can be reliably transferred onto the conveyor disposed on the downstream side.
Moreover, the structure of Claim 5 WHEREIN: The packaging apparatus which can convey articles | goods (tray) stably in a packaging apparatus can be comprised.

A packaging part 3 is provided above the elevator 2, and a film roll 4 is set on the side of the packaging part 3 (in a direction perpendicular to the conveying member of the conveying device B) and is fed out from the film roll 4. The film 4 ′ is pulled out by the film feed mechanism 5, cut to a predetermined length, and then transferred to the packaging unit 3.

In the packaging part 3, the left and right folding plates 6, 6 ', the rear folding plate 7, and the rear folding plate for folding the end portion of the film 4' covering the upper surface of the article W to the bottom side of the article are provided above the film feed mechanism 5. 7, a discharge pusher 8 for discharging the packaged article W and a front folding roller 9 are disposed.
The film feed mechanism 5 includes a pair of upper and lower endless elastic belts 5a and 5b that sandwich a side end in the width direction of the film, and a clamp plate 5c that presses the lower elastic belt 5b toward the upper elastic belt 5a. They are arranged on the front and back with the packaging part 3 in between.

  Further, in front of the front folding roller 9, a heat seal portion (discharge path) 10 for heating, bonding and discharging the overlapping portion of the end of the film folded to the bottom surface side of the article W and discharging means at the front portion thereof. 11, a console unit 12 on the machine frame 1, a label issuing unit (weighing label printer) 13 on the upper side of the heat seal unit (discharge channel) 10, and a heat seal unit (discharge channel). A label affixing device 14 is installed above 10.

  In the weighing and packaging apparatus A configured as described above, the article W placed on the article placement unit 15 of the conveying apparatus B is conveyed onto the elevator by the operation of the conveying apparatus B, and the article W conveyed on the elevator is The end of the film 4 ′ which is pushed up with respect to the film 4 ′ stretched on the packaging part 3 and covers the upper surface of the article W is formed by the rear folding plate 7 and the left and right folding plates 6 and 6 ′. Folded to the bottom side. Next, the front end of the film 4 ′ is folded to the bottom side of the article W by the front folding roller 9 while the article W is pushed horizontally toward the heat seal part (discharge path) 10 by the discharge pusher 8. The overlapping part of the film edge part folded in the bottom face side is heat-sealed by the heat seal part (discharge path) 10, and the article W packaged with the film is obtained.

  The label issuing unit 13 calculates the price of the article from the unit price set in advance based on data measured by placing the article W on the article placement unit 15 of the transport device B of the weighing packaging apparatus A. The label issuing unit 13 prints and issues the price and other article data on the label paper. The label issuing unit 13 'holds the printed and issued label substantially horizontally with the printing surface up. Is provided.

  The label sticking device 14 is composed of a suction part for the label held in the label issuing port 13 ', a drive mechanism for moving the label suction part, and a control means for controlling the operation of the drive mechanism. In addition, since the label issuing part 13 and the label sticking apparatus 14 are not directly related to this invention, detailed description is abbreviate | omitted.

Hereinafter, the conveyance device B that carries the article W into the apparatus will be described with reference to the drawings.
The conveying device B guides and moves the article placing unit 15 that places the article W, the conveying member 16 that conveys the article placed on the article placing unit 15 in the elevator direction, and the conveying member 16. It comprises a guiding means 17. A weighing means 18 is disposed at a vertically lower position of the article placing portion 15 so that the article placing portion 15 also serves as a weighing pan.

The article placement unit 15 is formed in a dish shape having a size covering the entire surface of the weighing means 18 disposed below by the synthetic resin material, and the placement surface 15a on which the article W is placed is arranged in parallel in the transport direction. It is formed in the convex shape arranged. That is, a groove portion 15b having a predetermined width is formed on the surface of the article placement portion 15, and the upper surface of the convex portion sandwiched between the groove portions 15b is the placement surface 15a.
The groove portion 15b is formed by injection molding such that the entire material thickness of the article placement portion 15 is substantially uniform including the groove portion, or a method of excavating the groove portion 15b portion from the material thickness, etc. In any case, the groove portion 15b in which the conveyance claw portion of the conveyance member 16 that presses and conveys the article W is located below the placement surface 15a on which the article W is placed is sufficient.

  As shown in FIG. 3A, the placement surface 15a is formed at substantially constant intervals throughout the width direction of the article placement unit 15 (width in a direction perpendicular to the transport direction), or the article placement unit 15 For example, as shown in FIG. 3 (b), it is arranged and concentrated only at a substantially central portion in the width direction of the article placement portion 15, or as shown in FIG. As shown in (c), it may be arranged in a concentrated manner in the substantially left half of the article placement portion 15 in the width direction. 3B and 3C, when the placement surface 15a is concentrated and arranged in a specific region in the width direction of the article placement portion 15, it is partitioned by the groove portion 15b or the groove portion 15b. The raised convex portion can be shown to the operator as a place for placing the article so that the operator can place the article in place. In addition, when the placement surface 15a described above is arranged and concentrated in a specific area, the position differs depending on the device arranged on the downstream side of the transport device. In the case of the position, it differs depending on the left side alignment, the right side alignment, or the center position.

  Further, on the upstream side in the conveying direction in the article placing portion 15, a bank 15c for rear end positioning when placing the article W is formed to project over the entire length in the width direction. The bank 15c is also formed with a notch for the transport claw 16b of the transport member 16 to pass through. When the measurement sensor 19 for measuring the width dimension of the article W placed on the article placement portion 15 is installed, the cutout portion does not interfere with the measurement by the bank 15c. In addition, the width dimension of the bank formed between the notch portions is adjusted as appropriate (for example, for measuring the width dimension of the article, refer to Japanese Patent No. 2790098).

The conveyance member 16 that conveys the article W placed on the placement surface 15a is configured such that the conveyance claw portion 16b protrudes in a comb-like shape on a rod rod 16a having a length that crosses the width direction of the article placement portion 15. Formed and configured.
The conveying member 16 may be formed by integrally forming the rod rod 16a and the conveying claw portion 16b by punching a metal plate, or may be integrally formed of a resin molded product, as shown in FIGS. 6 (a) and 6 (b). As shown, the rod rod 16a and the conveyance claw portion 16b may have separate structures, and the conveyance claw portion 16b may be detachably attached to the rod rod 16a by screwing. In addition, the method of detachably connecting both members is not limited to screwing, and any method such as clip clamping or insertion type may be used. When the transport claw portion 16b is detachably attached to the rod rod 16a, the transport claw portion can be easily attached only to a necessary position corresponding to the position of the mounting surface. When a part is damaged or deformed, it can be returned to a usable (conveyed) state by replacing only the corresponding conveying claw part. Further, the size (horizontal width) of the transport claw portion 16b may be varied in size without being uniform.

  By making the conveyance claw portion 16b detachable from the rod rod 16a as described above, the same effect as that obtained when the groove portion 15b is provided at, for example, the substantially central position of the conveyance device can be obtained without changing the article placement portion 15. Can do. That is, when it is desired to place the tray at a substantially central position, if only the conveyance claw portion 16b at the substantially central position of the rod rod 16a is left and the conveyance claw portion 16b at the side is removed, the conveyance claw portion 16b is approximately at the center. Therefore, the article is inevitably conveyed only at that position, and the operator can implicitly indicate the position where the article is placed on the article placement unit 15. When the position of the groove 15b is changed as described above, it is necessary to prepare in advance the article placement portion 15 having a different groove 15b and a conveying member 16 corresponding thereto, and attach it to the apparatus. If the position of the claw portion 16b is changed, only one type of the article placement portion 15 is prepared, and the position of the conveyance claw portion 16b is changed so that the position of the article placement portion 15 is substantially the center position or the left and right side ends. The article can be placed on the part.

The transport member 16 has the transport claw portion 16b intersecting the mounting surface of the article placement portion 15 at a substantially right angle, and the front end of the transport claw portion 16b is in the groove portion 15b of the article placement portion 15. It is arranged so as to move from upstream to downstream in a positioned state, and its conveying member 16 is continuous over a flat guide plate 20 arranged on the downstream side of the article placing portion 15 as shown in FIG. And can be moved.
Moreover, the conveyance nail | claw part 16b located in the groove part 15b may be a case where the lower end part (part) of the conveyance claw part 16b is located in (inserted into) the groove part 15b as shown in FIG. When the vertical width of 16a is large and the lower edge of the rod rod 16a is located in the vicinity of the surface of the mounting surface 15a, it is positioned (inserted) into the groove 15b up to the base of the conveying claw 16b. It may be.

  The flat guide plate 20 is formed in parallel with the groove portion 20a on the flat plate, like the groove portion 15b of the article placement portion 15, and the groove portion 20a is arranged so as to be aligned with the groove portion 15b of the article placement portion 15. Further, the depth of the groove 20a is formed such that the conveying claw 16b of the conveying member 16 that moves while being positioned in the groove 15b of the article placing portion 15 can move continuously as it is. Thereby, the article W placed on the placement surface 15a of the article placement portion 15 is pushed by the conveyance claw portion 16b of the conveyance member 16 located in the groove portion 15b of the placement surface 15a, and the article placement portion 15 From the flat guide plate 20 to the elevator 2.

As shown in FIG. 1, the guiding means 17 for guiding and moving the conveying member 16 from above the article placing portion 15 to the flat guide plate 20 is a flat plate from the upstream side of the article placing portion 15. The drive unit 21 is moved over the downstream side of the guide plate 20 and the guide unit 22 is configured to horizontally guide the conveying member 16 while maintaining the transport member 16 at a certain level (height).
The drive unit 21 has a pair of left and right sprockets 21a disposed at two locations on the upstream side of the article placement unit 15 and the downstream side of the flat guide plate 20, and a traveling chain is connected to each of the left and right rows of sprockets 21a. The traveling chain 21b rotates endlessly by winding 21b and driving one of the sprockets 21a with a motor 21c. The rod 16a of the conveying member 16 is connected and fixed via a bracket 21d across the pair of left and right traveling chains 21b.
The guide unit 22 guides the conveying member 16 moved by the driving unit 21 so as to move at a certain level without being displaced in the vertical direction, and guides the left and right end portions of the bar rod 16a of the conveying member 16. It arrange | positions facing right and left so that it may support.

In addition, a plurality (two in the illustrated example) of the conveying members 16 are attached to the traveling chain 21b of the driving unit 21 at intervals in the circumferential direction, and the article W is efficiently made by one rotation of the traveling chain 21b. It is configured so that it can be transported well (two in the illustrated example).
Note that the transport member 16 has a front position (initial position) on the upstream side of the article placement unit 15 so that the conveyance member 16 moves and contacts the rear side of the article W after the article W is placed on the article placement unit 15. It is configured to stop and wait at. As a configuration for stopping at the initial position, an initial position sensor 27 is disposed below the upstream side of the article placement unit 15, and driving is performed when the initial position sensor 27 detects the conveyance claw portion 16 b of the conveyance member 16. The unit 21 is stopped.

The member that guides the article W from the article placement unit 15 to the elevator 2 is not limited to the flat guide plate 20 shown in FIGS. 1 and 2, and is configured by a belt conveyor 23 that is driven and rotated as shown in FIG. 4, for example. May be. In that case, since the conveyance surface (belt surface) of the belt conveyor 23 is set at the same level as the placement surface 15a of the article placement unit 15 located on the upstream side, the conveyance member 16 is the same as in the previous embodiment. In the case where the conveyance claw portion 16b is moved forward with the conveyance claw portion 16b positioned in the groove portion 15b of the article placement portion 15, the conveyance claw portion 16b collides with the belt conveyor 23.
Therefore, in the case of the belt conveyor 23, after the article W is transferred from the article placement unit 15 to the belt conveyor 23, the function of pushing the article W by the conveying member 16 is not necessary. The section 21 and the guide section 22 are configured to guide the transport claw section 16b upward from the groove section 15b and away from the belt conveyor 23 at a position before the end of the article placement section 15.

When the article placement unit 15 is composed of a single sheet, when the conveyance member 16 is located within the range of the article placement unit 15, the conveyance member 16 obstructs the article placement unit. 15 cannot be removed from the conveying device B.
Therefore, as shown in FIGS. 5A and 5B, the article placement portion 24 is divided into two front and rear members 24a and 24b at a substantially central portion in the transport direction, and the front and rear members 24a and 24b are connected in the groove portion 15b. The piece 25 is screwed 26 so as to be divided. As a result, even when the transport member 16 is positioned within the range of the article placement portion 24 and is stopped, the article placement portion 24 can be removed from the front member 24a and the rear member 24b by loosening the screw 26 and removing the connecting piece 25. And can be detached from the transfer device B. Further, the connection of the front member 24a and the rear member 24b is made not to support the movement of the conveying claw portion located in the groove portion. The connection between the front member 24a and the rear member 24b is not limited to the screwing shown in the figure, and can be selected as appropriate.

  In the transport device having the above-described configuration, the operator inevitably has an article by collecting and placing the placement surface 15a of the article placement unit 15 (or 24) at a substantially central portion in the width direction (see FIG. 3B). W is placed at the approximate center in the width direction of the transfer device B. And when the packaging part 3 is arrange | positioned in the back | latter stage of the conveying apparatus B, the articles | goods W are pushed up to the film 4 'stretched by the packaging part 3 by the raising of the elevator 2, and the upper surface of the articles | goods W is covered with film 4'. When the end of the film 4 ′ is folded and packaged on the bottom side of the article with the left and right folding plates 6, 6 ′ and the rear folding plate 7, the article W is placed at the substantially central portion of the film 4 ′ stretched on the packaging part 3. As a result, the film can be packaged with an equal amount of film on the left and right.

The present invention is not limited to the illustrated embodiment, and can be appropriately changed without departing from the gist of the present invention.

As a result, the convex portions on which the articles are placed are densely provided at substantially the center position of the transport device, and the operator can more easily grasp the positions on which the articles are placed. In this case, the size of the corresponding conveying claw portion 16b needs to be large enough to be positioned in the width of the narrowed groove portion 15b.

(5) Prepare a plurality of article placement sections 15 having different positions of the grooves 15b formed in the article placement section 15 of the above embodiment, that is, the positions of the convex portions on which the articles are placed, for example, In a conveying apparatus that often conveys articles having a large lateral width, the article-loading unit 15 in which the convex portions on which the articles are placed is provided over the entire width direction is used to convey only small articles well. In the apparatus, for example, an article placement unit 15 provided with a convex portion for placing an article only at a substantially central position may be used.
(6) In the above embodiment, the article is moved in the carrying direction while supporting the carrying member so that it is pushed from the rear of the article. You may utilize this invention for the conveyance system of the type which moves to a conveyance direction, pinching | interposing from a direction (direction orthogonal to a conveyance direction). In other words, a groove portion that is continuously formed and bulges downward from the placement surface is provided, and the conveyance claw portion that sandwiches the left and right side surfaces of the article is located in the groove portion, and is moved while sandwiching both side surfaces of the article by the conveyance member. It may be. In this case, the width in the left-right direction of the convex portion for placing the article is shorter than the length of the width in the left-right direction of the article. Is positioned so as to protrude in the width direction from the convex portion, so that the article can be easily sandwiched between the conveying members.
