Description

[Technical field]

[0001] The present disclosure relates to a box-type transported article tipping device. [Background technology]

[0002] Cardboard boxes made by unfolding folded cardboard boxes, or cardboard box packages manufactured by packing products into cardboard boxes, are transported by conveyers or the like in the packaging and shipping processes, and may require the application of stickers or confirmation of whether stickers are attached. At this time, it becomes necessary to turn over the transported box (box-shaped transported item).

[0003] Patent Document 1 discloses a box inverting device that holds a box on a conveyor with a surface holding frame and inverts the box 180 degrees using a rotating frame corresponding to the height of the box to be inverted. Patent Document 2 discloses a box inverting device that feeds a box on a conveyor into a rotating drum that forms a transport path with its upper and lower surfaces sandwiched between belt conveyors, inverts the rotating drum, and then discharges it onto a conveyor on the exit side. Patent Document 3 discloses an inverting device that uses side holding frames positioned above and below a roller conveyor to move a transported object stopped at a predetermined position so that the two approach each other and sandwich the target transported object.

[0004] Furthermore, Patent Documents 4 and 5 disclose devices for inverting sheet-like articles such as paper bundles or cardboard bundles that are not boxes. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Japanese Patent Application Publication No. 9-12133 [Patent Document 2] JP 2012-96888 A [Patent Document 3] JP 2002-154641 A [Patent Document 4] JP 2019-147653 A [Patent Document 5] Utility model registration No. 3158249 Summary of the Invention [Problem to be solved by the invention]

[0006] The box inversion devices shown in Patent Documents 1 to 3 are limited in inversion direction to 180 degrees or 360 degrees. This is because they have holding mechanisms for holding the transported object from above and below, such as a frame, drum, and sandwiching guide, and when the transported object is inverted by 90 degrees, these mechanisms would impede the transported object from being transported downstream. In addition, in order to perform a 90-degree inversion, it is possible to add a mechanism for storing and opening and closing the holding mechanism, but this would complicate the device configuration and lead to high costs.

[0007] The present disclosure is an invention made in consideration of the above-mentioned problems, and has as its main object to provide a box-shaped transport item inversion device that is capable of performing both 90-degree and 180-degree inversions of box-shaped transport items with a simple device configuration. [Means for solving the problem]

[0008] The present disclosure provides a box-shaped transport item inversion device for inverting a box-shaped transport item, the box-shaped transport item inversion device having a main body portion having a pair of first pillars arranged spaced apart from each other in a first direction and a support portion connected to the pair of first pillars and arranged along a floor surface, a holding portion capable of holding the box-shaped transport item and having a first plate portion and a second plate portion arranged perpendicular to the first plate portion, the first plate portion being fixed to the main body portion and movable in the vertical direction along the first pillars and rotatable around the first direction as an axis of rotation, and an extendable lifting portion having one end rotatably fixed to the bottom surface of the first plate portion of the holding portion and the other end rotatably fixed to the support portion of the main body portion. Effect of the Invention

[0009] According to the present disclosure, it is possible to provide a box-shaped article inverting device that is capable of performing both 90-degree and 180-degree inversions of a box-shaped article with a simple device configuration. [Brief description of the drawings]

[0011] The following describes the embodiments of the present disclosure with reference to the drawings. However, the present disclosure can be implemented in many different forms, and should not be interpreted as being limited to the description of the embodiments exemplified below. In addition, the drawings may be schematic in terms of the width, thickness, shape, etc. of each part compared to the actual form in order to make the explanation clearer, but these are merely examples and do not limit the interpretation of the present disclosure. In this specification and each figure, elements similar to those described above with respect to the previous figures may be given the same reference numerals, and detailed explanations may be omitted as appropriate.

[0012] In this specification, when describing a mode in which another component is disposed on a certain component, the term "above" or "below" is used, unless otherwise specified, to include both a case in which another component is disposed directly above or below a certain component so as to be in contact with the component, and a case in which another component is disposed above or below a certain component with another component interposed therebetween. Also, in this specification, when describing a mode in which another component is disposed on the surface of a certain component, the term "on the surface side" or "on the surface" is used, unless otherwise specified, to include both a case in which another component is disposed directly above or below a certain component so as to be in contact with the component, and a case in which another component is disposed above or below a certain component with another component interposed therebetween.

[0013] In this specification, the "box-shaped transport object inverting device" is also simply referred to as the "inverting device." Furthermore, "90-degree inversion" means that the orientation of the box-shaped transport object is rotated so that it is in a position in which it is inverted once (90 degrees) around one side of the box-shaped transport object as a fulcrum. "180-degree inversion" means that the box-shaped transport object is rotated so that it is in a position in which it is inverted twice (180 degrees) around one side of the box-shaped transport object as a fulcrum (a position in which it is upside down).

[0014] The box-type transported article inverting device of the present disclosure will be described below. Fig. 1 is a schematic front view showing an example of a box-type transported article inverting device of the present disclosure. Fig. 2 is a schematic top view of the box-type transported article inverting device shown in Fig. 1. The box-type transported article inverting device 100 shown in Fig. 1 has a main body section 1, a holding section 2, and a lifting section 3. The box-type transported article inverting device 100 is a device that inverts a box-type transported article P transported by an upstream transport device 50A by 90 degrees or 180 degrees and discharges it to a downstream transport device 50B.

[0015] The main body 1 has a pair of first pillars 11 spaced apart from each other in the first direction D1, and a pair of second pillars 12 arranged upstream (toward the upstream conveying device 50A) of the first pillars 11 and spaced apart from each other in the first direction 11. The main body 1 has a support portion 13 connected to the pair of first pillars 11 and disposed along the floor surface F. The main body 1 also has a first connecting portion 14 extending in the first direction D1, connecting the first pillars 11 to each other, and serving as a rotation axis of the holder.

[0016] The holding unit 2 has a first plate portion 21 and a second plate portion 22 arranged perpendicular to the first plate portion 21, and defines a space capable of holding a box-shaped transport object P. The first plate portion 21 of the holding unit 2 is fixed to the main body portion 1 so as to be movable in the vertical direction along the first support pillar 11 and to be rotatable about a first direction D1 (first connecting portion 14) as a rotation axis.

[0017] The lifting unit 3 has one end connected to the bottom surface S of the first plate portion 21 of the holding unit 2. 21 One end is rotatably fixed to the support portion 13 of the main body portion 1, and the other end is rotatably fixed to the support portion 13 of the main body portion 1, and the member is extendable and contractible.

[0018] The box-type transport object inverting device 100 has a protective member 4 attached so as to be movable up and down along a pair of second support columns 12. The protective member 4 is linked to the holding unit 2 by a wire 6 via an idler 5 (5a, 5b) so as to rise when the holding unit 2 rotates up and to fall when the holding unit 2 rotates down. The protective member 4, the idler 5 (5a, 5b) and the wire 6 function as an input prevention mechanism that prevents the next box-type transport object P to be transported from being input into the inverting device 100 when the holding unit 2 holding the box-type transport object P rotates up.

[0019] Furthermore, the protective member 4, the idler 5 (5a, 5b) and the wire 6 also function as an origin return mechanism that applies a downward force to the holding part 2 and compresses the extended lifting part 3. That is, in FIG. 1, the above-mentioned insertion prevention mechanism and the above-mentioned origin return mechanism are integrated.

[0020] The operation mechanism when the box-shaped transport object is turned over 180 degrees using the box-shaped transport object turning device of the present disclosure will be described in detail with reference to Figures 3 and 4. As shown in Figures 3 and 4, there are four stages: input of the box-shaped transport object (Figure 3(a)), rotation of the box-shaped transport object (Figure 3(b)), discharge of the box-shaped transport object (Figure 4(a)), and return of the turning device to the origin (Figure 4(b)).

[0021] First, as shown in Fig. 3(a), a box-shaped object P conveyed by the upstream conveying device 50A is fed into the box-shaped object inverting device 100 of the present disclosure. At this time, the lifting section 3 is in a retracted position compressed to its limit. Therefore, the holding section 2 is in a lowered lower limit position, and the protective member 4 is in a lowered lower limit position, so that the holding section 2 receives the box-shaped object P fed from the upstream conveying device 50A.

[0022] 3(b), as the lifting / lowering unit 3 extends, the holding unit 2 rotates and rises (rotational rise) around the first direction D1 (first connecting unit 14) as the rotation axis, and rotates the box-shaped transported object P toward the downstream transport device 50B. Here, as the holding unit 2 rotates and rises, the protection member 4 rises.

[0023] Next, as shown in FIG. 4(a), when the lifting section 3 reaches the maximum extended position, the holding section 2 reaches its upper limit, and the box-shaped transported object P is discharged to the downstream conveying device 50B by its own weight. At this time, the box-shaped transported object rotates with the end of the downstream conveying device 50B as a fulcrum. This allows the box-shaped transported object P to be turned 180 degrees from the direction in which it was transported by the upstream conveying device 50A. As the holding section 2 reaches its upper limit due to the box discharge, the protective member 4 also reaches its upper limit, and the next box-shaped transported object P can be prevented from being input from the upstream conveying device 50A to the turnover device 100.

[0024] Next, as shown in FIG. 4(b), the lifting section 3 is compressed to the retraction limit, causing the holding section 2 to rotate and descend (rotational descent) toward the upstream conveying device 50A. As the holding section 2 rotates and descends, the protective member 4 descends to enable a box to be inserted from the upstream conveying device 50A. When the lowered holding section 2 reaches its lower limit, the compressed lifting section 3 reaches its retraction limit, and the lowered protective member 4 reaches its lower limit, the device returns to its initial state, which is the stage for inserting a box-shaped object (return to origin). This enables the next box-shaped object transferred from the upstream conveying device 50A to be reversed.

[0025] Next, the operation mechanism when the box-shaped transport object is turned over 90 degrees using the box-shaped transport object turning device of the present disclosure will be described in detail with reference to Figures 5 and 6. As shown in Figures 5 and 6, there are four stages: input of the box-shaped transport object (Figure 5(a)), rotation of the box-shaped transport object (Figure 5(b)), discharge of the box-shaped transport object (Figure 6(a)), and return of the turning device to its origin (Figure 6(b)).

[0026] First, as shown in Fig. 5(a), a box-shaped object P conveyed by the upstream conveying device 50A is fed into the box-shaped object inverting device 100 of the present disclosure. At this time, the lifting section 3 is in a retracted position compressed to its limit. Therefore, the holding section 2 is in a lowered lower limit position, and the protective member 4 is in a lowered lower limit position, so that the holding section 2 receives the box-shaped object P fed from the upstream conveying device 50A.

[0027] 5(b), as the lifting / lowering unit 3 extends, the holding unit 2 rises while rotating about the first direction D1 (first connecting unit 14) as the rotation axis, and rotates the box-shaped transported object P toward the downstream transport device 50B. Here, as the holding unit 2 rotates and rises, the protection member 4 rises.

[0028] 6(a), when the lifting section 3 reaches its output limit, the holding section 2 reaches its upper limit, and the box-shaped transport object slides by its own weight along the inclined holding section 2 and is discharged to the downstream conveying device 50B. This allows the box-shaped transport object P to be inverted 90 degrees from the direction in which it was transported by the upstream conveying device 50A. As the holding section 2 reaches its upper limit due to the box discharge, the protective member 4 also reaches its upper limit, and the next box-shaped transport object P can be prevented from being introduced into the inversion device 100 from the upstream conveying device 50A.

[0029] Next, as shown in Fig. 6(b), the lifting section 3 is compressed to the retraction limit, and the holding section 2 rotates and descends toward the upstream conveying device 50A. As the holding section 2 descends, the protective member 4 descends to enable a box to be inserted from the upstream conveying device 50A. The lowered holding section 2 reaches its lower limit, the compressed lifting section 3 reaches its retraction limit, and the lowered protective member 4 reaches its lower limit, returning the device to its initial state, that is, the box insertion stage (return to origin). This enables the next box-shaped object P transferred from the upstream conveying device 50A to be reversed.

[0030] According to the box-type transported article inverting device of the present disclosure, the box-type transported article can be inverted only by the weight of the box-type transported article and the thrust of the lifting and lowering unit. Therefore, a complex mechanism is not required, and the device configuration can be simple, resulting in a box-type transported article inverting device that can save space. Furthermore, according to the box-type transported article inverting device of the present disclosure, both 90-degree inversion and 180-degree inversion can be performed simply by changing the fixing position of the holding unit, the length of the lifting and lowering unit, the fixing position of the lifting and lowering unit, etc. Therefore, the box-type transported article inverting device of the present disclosure is a highly versatile inverting device that can invert the box-type transported article 90 degrees and 180 degrees with a simple device configuration.

[0031] The configurations and characteristics of the box-type transported article turnover device according to the present disclosure will be described in detail below.

[0032] 1. Main unit As shown in FIG. 1, the main body 1 in the present disclosure has a pair of first pillars 11 spaced apart from each other in a first direction D1 on a floor surface F. The main body 1 may also have a pair of second pillars 12 arranged upstream (on the upstream conveying device 50A side) of the first pillars 11 and spaced apart from each other in the first direction D1. The first pillars and the second pillars are members extending in the up-down direction. The up-down direction, for example, includes a downward direction that includes a directional vector in which gravity is directed, and the upward direction is the opposite direction to the downward direction. In particular, the up-down direction is preferably a vertical direction. The extension directions of the first pillars and the second pillars are preferably the same.

[0033] 1 and 2, the main body 1 has a support section 13 that is directly or indirectly connected to a pair of first columns 11 and disposed along a floor surface F. The support section 13 is preferably indirectly fixed to the pair of first columns 11 via another connecting section 15 (connecting section connecting the first columns 11 to each other) described later. One end of the lifting section 3 described later is rotatably fixed to the support section 13. The support section 13 is preferably a columnar member extending in a second direction D2 perpendicular to the first direction D1.

[0034] The distance between the pair of first support columns is not particularly limited as long as the box-shaped article can pass through it, that is, it is not particularly limited as long as it is greater than the width of the box-shaped article.

[0035] As shown in Fig. 1 and Fig. 2, the main body 1 preferably has a first connecting portion 14 that extends in the first direction D1, connects the first supports 11 to each other, and serves as a rotation axis of the holder 2. The first connecting portion 14 is preferably fixed so as to be movable in the vertical direction along the first supports 11. The first connecting portion 14 is fixed to the first supports 11 so as not to move in the vertical direction while the reversing device is in operation. On the other hand, when changing the reversing angle (90 degrees or 180 degrees) or the size of the box-shaped transported object, the height position of the connecting portion 14 is moved and adjusted so as to be the fixed position of the holder described later, and then fixed to the first supports 11.

[0036] As shown in Figures 1 and 2, the main body 1 may have other connecting portions 15, such as a connecting portion 14 extending in a first direction D1 and connecting the first pillars 11 to each other, and a connecting portion extending in a second direction D2 and connecting the first pillars 11 and the second pillars 12.

[0037] 2. Holding part The holding section in the present disclosure is a member capable of holding a box-shaped transport object, and moves up and down while rotating in response to the expansion and contraction of the lifting section described later. Specifically, when the lifting section expands, the holding section moves up while rotating toward the downstream transport device. On the other hand, when the lifting section compresses, the holding section moves down while rotating toward the upstream transport device. This allows the box-shaped transport object held by the holding section to be inverted and discharged to the downstream transport device. The holding section has a first plate section and a second plate section arranged perpendicular to the first plate section. The planar shapes of the first plate section and the second plate section are not particularly limited, but are, for example, rectangular shapes such as squares and rectangles. The material of the first plate section and the second plate section is not particularly limited, but examples include resin, wood, and the like. It is preferable that the placement surface of the first plate section has a predetermined friction force. This is because it is easier to apply a rotational force to the box-shaped transport object when performing a 180-degree inversion.

[0038] The first plate of the holding part is fixed to the main body so as to be movable in the vertical direction along the first support and to be rotatable around the first direction as a rotation axis. In the inversion device of the present disclosure, the first plate of the holding part is disposed on the downstream side and the second plate is disposed on the upstream side. As shown in FIG. 2, the holding part 2 may have a connection part 23 that is fixed to the first plate part 21, through which the first coupling part 14 is inserted and that is rotatable around the first coupling part 14. In this case, the first plate part 21 of the holding part 2 is fixed to the pair of first supports 11 via the first coupling part 14 and the connection part 23.

[0039] In the present disclosure, the fixed position of the holding part can be adjusted to select 90-degree inversion or 180-degree inversion. In the present disclosure, the "fixed position of the holding part" refers to the height position at which the first plate part of the holding part is fixed so as to be rotatable. For example, as shown in Figs. 1 and 2, in the case where the first plate part 21 is indirectly fixed to the first support 11 via the first connecting part 14, the fixed position refers to the height position of the first connecting part 14.

[0040] Specifically, as shown in Figures 1, 3 and 4, by making the fixing position H2 of the holding unit 2 lower than the height position H of the surface of the downstream conveyor 50B, when the box is discharged from the holding unit to the downstream conveyor 50B, the box-shaped transport object P can be rotated around the corner of the downstream conveyor 50B as a fulcrum, and can be turned 180 degrees from the orientation of the box-shaped transport object P on the upstream conveyor 50A. When turning the box 180 degrees, it is preferable that the angle θ1 (lower side) between the first member 21 in the holding unit 2 at the time of discharge (Figure 4(a)) and the first support 11 is, for example, 140° or more and 180° or less.

[0041] 5 and 6, by making the height position H2 of the holding unit 2 the same as or higher than the height position H of the surface of the downstream conveyor 50B, when the box-shaped object P is discharged from the holding unit 2 to the downstream conveyor 50B, the box-shaped object P slides and can be turned 90 degrees from the orientation of the box-shaped object P on the upstream conveyor 50A. When turning it over 90 degrees, the angle θ2 (lower side) between the first member 21 in the holding unit 2 and the first support 11 at the time of discharge (FIG. 6(a)) is, for example, greater than 90° and equal to or less than 120°, and preferably equal to or greater than 95° and equal to or less than 110°.

[0042] 3. Lifting section The lifting section in the present disclosure is not particularly limited as long as it is an expandable member. The lifting section has a function of rotating and raising the holding section to the downstream side by extending, and rotating and lowering the holding section to the upstream side by compressing. Examples of the lifting section include an air cylinder, a hydraulic cylinder, and an electric cylinder. Among them, an air cylinder is preferable. This is because the structure of the box-type transported object inversion device is simpler in a factory or the like equipped with an air compressor. In addition, when electricity is not used for the downstream transport device and the upstream transport device, a transport system that does not use electricity overall can be constructed and can be used in an explosion-proof environment.

[0043] As shown in FIG. 1, the lifting section in the present disclosure has one end connected to the bottom surface S of the first plate portion 21 of the holding portion 2. 21 The bottom surface S of the first plate portion 21 is fixed to the 21 The bottom surface S of the first plate portion 21 of the holding portion 2 is opposite to the surface on which the box-shaped transported object is placed. 21 2 and 7, the fixing position X of the lifting / lowering unit 3 is preferably on the second plate portion 22 side in the second direction D2. The "second plate portion 22 side in the second direction D2" refers to the fixing position X of the lifting / lowering unit 3 on the second plate portion 22 side in the second direction D2. 21 That is, in the present disclosure, the distance W between the end E1 of the first plate portion 21 on the first support 11 side and the fixed position X is X The width W of the first plate portion 21 in the second direction 21 Percentage of (W X / W 21 The ratio (W) is preferably 0.5 or more. X / W 21 ) may be 0.6 or more, 0.7 or more, 0.8 or more, or 0.9 or more. By setting the fixed position as described above, the rotational ascent of the holding part can be performed smoothly.

[0044] The other end of the lifting section in the present disclosure is rotatably fixed to the support section of the main body section. The fixing position of the lifting section relative to the support section of the main body section is not particularly limited. As shown in FIG. 1, the fixing position Y of the lifting section 3 relative to the support section 13 of the main body section 1 is preferably downstream of the position O of the first support column 11 in the second direction D2. When the height of the downstream conveyor 50B is low, for example, if the fixing position Y is the same as the position O of the first support column, it is necessary to shorten the length in which the rod of the cylinder is stored, and it is difficult to ensure the length of the lifting section when extended, which is necessary for 90-degree and 180-degree reversals. On the other hand, by the above-mentioned fixing position Y being downstream of the position O of the first support column 11 in the second direction D2, the length of the lifting section when extended, which is necessary for 90-degree and 180-degree reversals, can be ensured.

[0045] In the present disclosure, it is preferable that the ratio (L / H) of the distance L between the fixed position Y located downstream of the position O of the first pillar 11 and the position O of the first pillar 11 to the height H of the downstream conveyor 50B be arbitrarily determined in a range greater than 0 according to the available space at the site.

[0046] 4. Loading prevention mechanism The box-shaped transport object inverting device of the present disclosure preferably has an input prevention mechanism that prevents the next box-shaped transport object from being input into the inverting device when the holding part holding the box-shaped transport object rotates upward. By having the input prevention mechanism, it is possible to prevent the input of the box-shaped transport object from the upstream transport device when the holding part rotates upward, and box rotation by the holding part can be reliably performed. In particular, it is preferable for the mechanism to prevent the input of the next box-shaped transport object at least when the holding part reaches its upper limit position (when the box-shaped transport object is discharged). This is because when the holding part reaches its upper limit position, the gap between the holding part and the upstream transport device becomes wider, making it easier for the box-shaped transport object to be pinched between the inverting device and the upstream transport device or to fall.

[0047] The specific configuration of the throw-in prevention mechanism is not particularly limited. In Fig. 1, the throw-in prevention mechanism has a protection member 4, an idler 5 (5a and 5b), and a wire 6. The protection member 4 is connected to the holder 2 by the wire 6 via the idler 5 (5a and 5b).

[0048] With this configuration, the protective member 4 can be linked to the holding unit 2 by the wire 6 via the idlers 5 (5a, 5b) so that the protective member 4 rises when the holding unit 2 rotates upward and falls when the holding unit 2 rotates downward. Specifically, when the holding unit 2 rotates upward toward the downstream conveying device, the wire is pulled up by the thrust of the rotation, and the protective member 4 rises to the height of the box-shaped object to be conveyed next, making it possible to prevent the box-shaped object from being introduced from the upstream conveying device. Also, when the holding unit 2 rotates downward toward the upstream conveying device, the wire is pulled down by the weight of the protective member 4, and the protective member 4 descends below the upstream conveying device, making it possible to introduce the box-shaped object from the upstream conveying device.

[0049] The wire is preferably fixed to the bottom surface of the holding part. The bottom surface of the holding part refers to the surface opposite to the surface of the holding part on which the box-shaped transported object is placed. In particular, the bottom surface S of the first plate portion 21 of the holding part 2 21 It is preferable that the wire is fixed to the bottom surface of the second plate portion 22 of the holding unit 2. If the wire is fixed to the bottom surface of the second plate portion 22 of the holding unit 2, there is a possibility that the wire may get caught on a corner of the holding unit, especially when performing a 180-degree turn. Furthermore, it is preferable that the wire is disposed on the bottom surface of the first plate portion 21 closer to the second plate portion 22 side than the fixing position of the lifting / lowering unit 3. On the other hand, the wire may be fixed to the bottom surface of the second plate portion 22 of the holding unit 2.

[0050] 5.Origin return mechanism The box-type transported object inverting device of the present disclosure preferably has an origin return mechanism that applies a downward force to the holding portion and returns the extended lifting portion. By having the origin return mechanism, the holding portion that has rotated upward can be smoothly rotated downward. The origin return mechanism is not particularly limited in configuration as long as it has a mechanism that applies a vertically downward force to the holding portion and returns the extended lifting portion. In FIG. 1, the origin return mechanism has a protective member 4, an idler 5 (5a and 5b), and a wire 6. On the other hand, the origin return mechanism may be, for example, a weight attached to the holding portion 2.

[0051] In the present disclosure, as shown in Fig. 1, it is preferable that the protective member 4, the idler 5 (5a and 5b), and the wire 6 serve as both the above-mentioned insertion prevention mechanism and the above-mentioned origin return mechanism. In other words, it is preferable that the above-mentioned insertion prevention mechanism and the above-mentioned origin return mechanism are integrated. This makes it possible to make the device configuration simpler, thereby making it possible to reduce the size and cost.

[0052] 6. Box-type transport item inversion device The box-shaped transport object inverting device of the present disclosure is preferably used by being disposed between an upstream transport device and a downstream transport device. The upstream transport device is disposed upstream of the inverting device of the present disclosure, and is a device that transports the box-shaped transport object and inputs it into the inverting device of the present disclosure.
