Description

Technical Field

[0001] The present disclosure relates to the field of opening boxes, particularly cardboard transport packaging boxes. The present disclosure relates in particular not only to cutting devices for cutting the walls of boxes, but also to equipment for opening boxes, including this type of cutting device. This type of equipment is most often used in logistics centers or distribution centers to quickly open cardboard boxes containing goods.

Background Art

[0002] In the past, cardboard boxes were manually opened to extract the goods or products being transported from the cardboard box. This manual operation is time-consuming, sometimes dangerous, and highly likely to damage the products contained in the box, so logistics centers have gradually equipped themselves with equipment for automatically opening boxes.

[0003] These opening devices generally perform a cutting step in which a cutting tool with a blade makes a continuous cut or a pre-cut on the box.

[0004] The cutting device is generally attached to the head of a multi-axis robot.

[0005] Moreover, the plurality of boxes received at the inlet of the equipment often have different wall thicknesses. The cutting depth of the cutting tool is generally made to a dimension adapted to the median value of the wall thickness.

[0006] In one of the boxes, if the wall to be cut is thicker than the median value of this thickness, the cutting depth may not be sufficient to cleanly open the wall. In this case, manual intervention is required to finish opening the box, which impairs the effectiveness of the opening method.

Summary of the Invention

Problems to be Solved by the Invention

[0007] One object of the present disclosure is to propose a cutting device that eliminates the aforementioned drawbacks and can adapt itself to different wall thicknesses.

Means for Solving the Problems

[0008] The present invention achieves this object by a cutting device for cutting the wall of a box that extends along a longitudinal axis between a mounting portion for the head of a robot and a cutting member having a blade, the blade having at least one first cutting edge, and the cutting device a first part comprising a cutting member and a first support element, a second part that is movable in a translational motion relative to the first part along the longitudinal axis and includes a foot pad having a bearing surface, such that the foot pad is movable in a translational motion relative to the blade along the longitudinal axis and includes, the cutting device has at least one first cutting position and at least one second cutting position corresponding to at least two different cutting depths of the wall, and the blade projects axially beyond the foot pad when the cutting device is in the first cutting position or the second cutting position of the cutting device, in the first cutting position, the foot pad is at a first axial distance from the first support element, such that the blade extends beyond the foot pad over a first length corresponding to the first cutting depth, and in the second cutting position, the foot pad is at a second axial distance from the first support element such that the blade extends beyond the bearing surface over a second length corresponding to the second cutting depth, the first cutting depth being deeper than the second cutting depth, the cutting device further includes a selection device for selecting the first cutting position or the second cutting position.

[0009] It can be seen that the first length is longer than the second length. Thus, the cutting device according to the present disclosure provides at least two cutting depths. The first cutting depth is a deep cutting depth on the order of, for example, 7 mm, while the second cutting depth is a shallower cutting depth on the order of, for example, 4 mm.

[0010] The selection device is adapted to determine the minimum axial distance between the foot pad and the first support element from among the first axial distance and the second axial distance so as to select the cutting depth from among the first cutting depth and the second cutting depth.

[0011] It can be seen that the cutting depth is at most equal to the length of the part of the blade protruding beyond the bearing surface of the foot pad.

[0012] The cutting device according to the present disclosure can easily and quickly adapt to the thickness of the wall to be cut, so that qualitative cutting can be performed without stopping the equipment or providing several cutting devices in order to adapt to walls of different thicknesses.

[0013] Accordingly, the adjustment of the cutting depth is achieved via a selection device that can be actuated manually or automatically.

[0014] When performed automatically, the controller of the cutting equipment can receive a control signal representing the thickness of the wall of the box entering the equipment, for example, and control the selection device to select a cutting depth suitable for said thickness.

[0015] It can be seen that the depth adjustment can be performed quickly, for example, immediately after cutting the wall of the first box and before cutting the wall of the next box having a different thickness.

[0016] Accordingly, the cutting device according to the invention has the advantage of being able to quickly adapt to the wall thickness of the boxes entering the equipment for cutting and opening the boxes.

[0017] Moreover, it can be seen that the adjustment of the cutting depth is achieved by adjusting the length of the part of the blade protruding axially beyond the foot pad when the foot pad is pressing against the wall to be cut.

[0018] More precisely, the selection device has the function of limiting the length of the part of the blade protruding axially beyond the bearing surface of the foot pad.

[0019] During operation, the cutting device moves towards the box such that the bearing surface of the foot pad compresses the wall to be cut. The first part approaches the second part (which is compressing the wall to be cut), and then a slight downward pressure is applied to the cutting device so that the blade penetrates into the wall to be cut to a depth corresponding to the first cutting depth or the second cutting depth. At this time, the cutting depth, which is defined as the maximum distance between the lower end of the blade and the bearing surface, corresponds to the minimum distance between the foot pad and the first support element of the first part.

[0020] This minimum distance between the foot pad and the first support element is preferably achieved thanks to one or more stroke end stops that limit the axial movement of the second part relative to the first part during use.

[0021] Without departing from the scope of the present invention, the cutting device may have more cutting positions.

[0022] Preferably, the cutting device includes a stroke end stop element, which is retractable and has a deployed position where the second part compresses the stroke end stop element when the cutting device is in the second cutting position, and a retracted position where the stroke end stop element does not limit the axial movement of the second part relative to the first part.

[0023] It can be seen that when the stop element is in the retracted position, the axial movement of the first part relative to the second part is greater than when the stop element is in the deployed position. Thus, when the stop element is in the retracted position, the maximum distance between the lower end of the blade and the bearing surface is greater than when the stroke end stop element is in the deployed position and the second part is in contact with the stop element, which occurs when the bearing surface bears against the wall to be cut.

[0024] Thus, the stroke end stop element makes it possible to define the second cutting depth.

[0025] Preferably, the first part further includes an actuator for moving the stroke end stop element between its retracted and deployed positions.

[0026] This actuator is, for example, a pneumatic jack.

[0027] More preferably, the actuator is configured to move the stop element in a direction of movement transverse to the longitudinal axis. Preferably, the direction of movement is perpendicular to the longitudinal axis.

[0028] Preferably, the actuator is attached to a second support element of the first part, and the second support element is arranged at a distance above the first support element.

[0029] Preferably, the first support element is connected to the second support element using at least one spacer.

[0030] Preferably, the stroke end stop element is located between the first support element and the second support element.

[0031] Optionally, the first part further includes a load absorbing element located axially above the stroke end stop element, and in the deployed position, the stroke end stop element is in contact with the load absorbing element.

[0032] The load absorbing element is, for example, a metal plate integrated with the second support element.

[0033] It can be seen that the load absorbing element can prevent damage to the second support element when the second part abuts against the stroke end stop element.

[0034] Preferably, the second part further includes at least one first arm integrally formed with a foot pad and slidably mounted along the longitudinal axis with respect to the first support element. The first arm crosses the first support element, and the second part further includes a contact element connected to the first arm. In the first arm, the contact element abuts against the stroke end stop element when the cutting device is in the second cutting position.

[0035] It can be seen that the contact element is arranged to lean against the stroke end stop element when the stroke end stop element is in the deployed position.

[0036] Conversely, when the stroke end stop element is in the stored position, the contact element does not cooperate with the stroke end stop element so that the movement of the contact element is not restricted by the stroke end stop element.

[0037] Preferably, the first support element includes a first guide sleeve in which the first arm slides.

[0038] Preferably, the second part further includes a second arm integrated with the foot pad and slidably mounted with respect to the first support element. The second arm crosses the first support element. The first arm and the second arm are located on both sides of the cutting member, and the contact element constitutes an element connecting the first arm and the second arm together. It can be seen that the contact element is arranged to abut against the stroke end stop element when the cutting device is in the second cutting position. Preferably, the first part further includes a stroke end stop member arranged to stop the stroke of the foot pad at the first position of the cutting device when the stroke end stop element is in the stored position. With respect to the longitudinal axis, the stroke end stop element is located between the stroke end stop member and the foot pad.

[0039] Preferably, the stroke end stop member is attached to the second support element. The axial extension of the stroke end stop member can be adjusted manually, for example, by screwing, to adjust the first cutting depth. Preferably, the foot pad further includes at least one first support roller that abuts against the wall of the box to facilitate the movement of the foot pad on the wall to be cut while providing pressure on the wall to be cut. The first support roller is rotatably mounted on a shaft engaged with the foot pad.

[0040] Preferably, the foot pad includes a second support roller, and the first support roller and the second support roller are located on both sides of the blade.

[0041] Preferably, the blade further includes a second blade tip on the side opposite to the first blade tip, and the blade preferably has a pointed tip shape.

[0042] The blade preferably extends in a plane perpendicular to the axis of the first support element.

[0043] Preferably, the first part is movable relative to the mounting part in a translational motion along the longitudinal axis, and the mounting part is connected to the first part using a spring member.

[0044] By mounting it flexibly in this way, it becomes possible to follow the possibility of the height of the box changing.

[0045] Preferably, the second support element and the mounting part are attached to each other using a member for guiding in a translational motion that preferably extends parallel to the longitudinal axis by being positioned on both sides of the spring member.

[0046] Preferably, the cutting member further includes a blade holder having controllable jaws, and the blade is held by the controllable jaws.

[0047] The controllable jaws can be actuated when opening and / or closing by means of a pneumatic jack.

[0048] The movement direction of the controllable jaws is preferably perpendicular to the plane of the blade.

[0049] To ensure that there is a new blade in the tool's replacement blade magazine, the first part further includes a blade presence sensor. The blade presence sensor is preferably mounted in the first support element. When the cutting device is brought above the magazine, the blade presence detector detects whether a replacement blade actually exists in the magazine.

[0050] Preferably, in a plane perpendicular to the longitudinal axis, the foot pad has a "U" - shaped portion with which the cutting member engages, and the "U" - shaped portion is open laterally.

[0051] Preferably, the outer edge of the "U" - shaped part is attached to the first arm part and the second arm part. By being opened in this way, it becomes possible to more easily approach the blade and facilitate maintenance.

[0052] More preferably, the blade presence sensor is mounted next to the first support element, and the "U" - shaped part is open laterally towards the blade presence sensor.

[0053] This arrangement makes it possible to improve the detection of the presence of a blade in the blade magazine. The present invention further relates to at least one transporter for moving the box in the moving direction, one cutting robot comprising a cutting device according to the present disclosure, the cutting robot having a head attached to the mounting head of the cutting device and is related to a facility for opening a box.

[0054] The facility preferably but not exclusively further includes a controller arranged to control the selection device based on a control signal presenting the thickness of the wall of the box.

[0055] Preferably, the facility further includes a cutting station including a cutting robot and a station for opening the box including a gripping robot with a suction cup for opening the cutting wall, and the station for opening the box is positioned downstream of the cutting station.

[0056] Preferably, the facility further includes a replacement blade magazine. This magazine includes a new blade and preferably a support for receiving a worn blade. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE INVENTION

[0059] The facility 10 for opening a box, specifically a cardboard box containing articles, is illustrated in FIG. 1. In this example, the box 100 is a cardboard paper having a well-known generally parallelepiped shape that is traditionally used for transporting articles. The facility 10 has the function of automatically opening such a box, and more precisely, the upper wall 102 of the box. The facility 10 receives the box 100 at the inlet of the facility 10 and supplies, at the outlet of the facility 10, a box in which the upper wall 102 has an opening 104.

[0060] The facility 10 has a main conveyor 12 that extends in the longitudinal direction D and has a moving direction S between the upstream portion 12a and the downstream portion 12b of the main conveyor 12. In this example, it has a roller conveyor 14.

[0061] In this Figure 1, a reference system XYZ is shown. The longitudinal direction D is parallel to the axis X, the width of the main conveyor extends along the axis Y, and the axis Z is in the vertical direction.

[0062] In the following description, the terms upstream and downstream are considered with reference to the moving axis S.

[0063] In this example, considering the moving direction S, from upstream to downstream, the facility 10 according to a representative embodiment continuously includes a measurement station 20, a cutting station 30, and a discharge station 40.

[0064] It can be seen that the box is first placed in the upstream portion 12a of the main conveyor 12, that is, upstream of the measurement station 20. The open box then exits via the downstream portion 12b of the discharge station 40.

[0065] Since it is located downstream of the measurement station 20, the cutting station 30 includes a cutting robot 32 equipped with a cutting device 200 to be described in more detail below. The cutting robot 32 is, in this example, a multi-axis robot that enables the cutting device 200 to move in space along the axes X, Y, and Z. As will be explained below, the cutting device 200 includes two cutting depths to adapt itself to the thickness of the upper wall 102 to be cut. In this example, it is defined that the information related to the upper wall to be cut is transmitted to the controller of the facility via a control signal.

[0066] The discharge station 40 located downstream of the cutting station 30 includes, in this example, a gripping robot 42 similar to the cutting robot. The gripper 42 is equipped with a gripping device 44. In this example, the gripping device 44 includes a suction member that appears in the form of a suction cup.

[0067] According to the present disclosure, the gripping device 44 grips the wall portion 110 cut by the cutting device 100 and is moved to pull the wall portion away from the main body of the box. Next, the cut portion is placed on a sub-conveyor 60 that extends parallel to the main conveyor, but in this non-limiting example has a moving direction S' opposite to the moving direction S of the main conveyor 12.

[0068] The cutting device 200 according to the first representative embodiment will be described with reference to FIGS. 2 to 9.

[0069] A reference system X'Y'Z' is shown, and the axis Z' of the reference system is parallel to the longitudinal axis A of the cutting device.

[0070] As described above, the cutting device 200 has a function of cutting the upper wall of the box 100. The cutting device 200 extends along the longitudinal axis A between a mounting portion 202 intended to be mounted on the head 33 of the cutting robot 32 and a cutting member 204 having a blade 206.

[0071] The blade 206 includes a first cutting edge 206a that defines a cutting direction along the axis X' orthogonal to the axis Z'.

[0072] The axis X' is oriented in the direction defined by the first cutting edge 206a, while the axis Y' is perpendicular to the axes X' and Z'.

[0073] In this example, the blade 206 has a pointed tip shape and further includes a second cutting edge 206b on the opposite side of the first cutting edge 206a.

[0074] The cutting device 200 includes a first portion 210 including the cutting member 204 and a first support element 212. In this example, the cutting member 204 is attached to the first support element 212.

[0075] The cutting member 204 further includes a blade holder 205 having controllable jaws 207. The blade 206 is held by the controllable jaws 207 of the blade holder. The opening of the controllable jaws 207 for releasing the blade is controllable by a controller of the equipment.

[0076] In this example, the first support element 212 appears to be in the form of a plate having a central opening 213 that is attached to the upper surface of the first support element 212 while the cutting member 204 engages therewith.

[0077] The first portion 210 further includes a second support element 214 that is spaced above the first support element 212 using a spacer 215. In this example, the spacer 215 takes the form of a rod extending parallel to the longitudinal axis A.

[0078] Moreover, in this example, the first portion 210 is movable relative to the mounting portion 202 in a translational motion along the longitudinal axis A. To achieve this purpose, the first portion 210 and the mounting portion 202 include a first member and a second member 216 for guiding in a translational motion, which include a shaft portion 217 attached to the second support element 214 and engaging with a covering 218 belonging to the mounting portion 202. The shaft portion 217 is designated to move freely in the covering 218 parallel to the axis Z' in a translational motion.

[0079] Furthermore, the mounting portion 202 is connected to the second support element 214 using a spring member 220 located between the first portion and, more particularly in this example, between the shaft portions 217. In this example, the spring member is a compression spring extending along the axis Z'. As its function, the spring member has the function of absorbing the movement of the foot pad along the axis Z' due to the possibility of variation in the height of the box.

[0080] Therefore, it can be seen that the blade 206 is movable relative to the mounting portion 202 along the longitudinal axis A via the spring member 220.

[0081] The cutting device 200 further includes a second portion 222 that is movable relative to the first portion 210 in a translational motion along the longitudinal axis A. The second portion 222 includes a foot pad 224 having a lower surface 225. The foot pad is formed to compress the wall of the box to be cut.

[0082] Therefore, it can be seen that the foot pad 224 is movable in a translational motion with respect to the blade 206 along the longitudinal axis A. To achieve this purpose, the second part 222 includes a first arm 226 and a second arm 228 formed integrally with the foot pad 224, and the first arm 226 and the second arm 228 are slidably mounted with respect to the first support element 212 parallel to the longitudinal axis A. It is noted that the first arm 226 and the second arm 228 engage with the guide sleeves 230, 232 attached to the first support element 212. Moreover, it is noted that the first arm 226 and the second arm 228 are located on both sides of the cutting member 204. As shown in detail in FIG. 2, the first arm 226 and the second arm 228 cross the first support element 212 so as to project above the first support element 212. As a result, the first arm 226 and the second arm 228 are connected together by a connecting element 234 located between the first support element 212 and the second support element 214. In this example, the connecting element 234 forms a bar extending along the axis X'.

[0083] The spring member 220 has a function of absorbing movement along the axis Z' due to the possibility of the height of the box varying.

[0084] Referring to FIGS. 3 and 4, it is noted that the first part 210 further includes a blade presence sensor 240 attached to the first support element 212. In the figure, the beam 241 of the blade presence sensor 240 is schematically shown. The function of the blade presence sensor 240 is to ensure that there is a replacement blade in the replacement blade magazine 74 of the equipment.

[0085] Referring to FIGS. 3 to 5, considering the plane P perpendicular to the longitudinal axis A, it is noted that the foot pad 224 has a "U" - shaped portion with which the cutting member 204 engages, and the "U" - shaped portion opens laterally towards the blade presence sensor 240.

[0086] In addition, the foot pad 224 further includes a first support roller 201 and a second support roller 203 located on both sides of the blade 206, and the first roller 201 and the second roller 203 are arranged to compress the wall of the box to be cut during the cutting operation. The first roller 201 and the second roller 203 also serve to facilitate the movement of the foot pad during the cutting operation.

[0087] Without departing from the scope of the present invention, the support roller can be replaced with the boss of the foot pad 224.

[0088] According to the present disclosure, the cutting device 200 has at least one first cutting position and at least one second cutting position corresponding to at least two different cutting depths of the wall, and the blade 206 projects axially beyond the foot pad when the cutting device is in the first cutting position or the second cutting position of the cutting device. In this example, the blade 206 projects axially beyond the first support roller and the second support roller.

[0089] The bearing surface is constituted by the circumferential surfaces of the first support roller and the second support roller in this example.

[0090] In FIGS. 2 and 3, the cutting device is illustrated in its first cutting position, and the cutting depth is on the order of 7 mm, while in FIGS. 3 and 5, the cutting device 200 is illustrated in its second cutting position, and the second cutting depth is on the order of 4 mm.

[0091] In the first cutting position illustrated in FIGS. 2, 4, 6, and 8, the foot pad 224 is at a first axial distance d1 from the first support element 212, and as a result, the blade 206 extends axially beyond the foot pad 224 and, in this example, beyond the first support roller 201, over a first length corresponding to the first cutting depth p1.

[0092] Furthermore, at the second cutting positions illustrated in FIGS. 3, 5, 7, and 9, the foot pad 224 is at a second axial distance d2 from the first support element 212, such that the blade 206 extends beyond the foot pad outwardly, in this example beyond the first support roller 201, over a second length corresponding to the second cutting depth p2. It can be seen from the figures that the first cutting depth p1 is deeper than the second cutting depth p2.

[0093] The cutting device 200 also includes a selection device 260 for selecting the first cutting position or the second cutting position. To achieve this purpose, in this example, the selection device 260 includes a retractable end stop element 262.

[0094] The end stop element 262 has a deployed position illustrated in FIGS. 3, 5, 7, and 9, where a second portion presses against the end stop element 262 when the cutting device is in the second cutting position. More specifically, the connecting element 234 forms a contact element that comes into contact with the end stop element 262 when the cutting device is in the second cutting position.

[0095] As described above, when the first portion is pressed by the support rollers 201, 203 against the wall to be cut, the second portion then moves axially towards the mounting portion until the connecting element 234 presses against the end stop element 262, such that the second portion is movable relative to the first portion so as to define the second cutting depth. In this example, the end stop element 262 generally has a disk shape including a lower flat surface and an upper flat surface, the lower flat surface forming an end stop for the connecting element 234, while the upper flat surface presses against the second support element 214.

[0096] To avoid damaging the second support element 214, the first part also includes a load absorbing element 264 that is axially located above the stroke end stop element. The load absorbing element is a steel part housed within the second support element 214. In the deployed position, the stroke end stop element is in contact with the load absorbing element 264, and as a result, it can be seen that the impact imparted by the connecting element 234 on the stroke end stop element 262 is absorbed by the load absorbing element 264.

[0097] Moreover, the stroke end stop element 262 includes a stowed position, illustrated in FIGS. 2, 4, 6, and 8, where the stroke end stop element does not limit the axial movement of the second part relative to the first part. In other words, in the stowed position, the stroke end stop element 262 does not cooperate with the connecting element 234.

[0098] Thus, the connecting element 234 can move axially beyond the stop element relative to the first part. The first part also includes a stroke end stop member 266 that stops the movement of the foot pad 224 at the first cutting position when the stroke end stop element 262 is in the stowed position. Referring to FIGS. 6 and 8, it can be seen that the connecting element 234 abuts against the stroke end stop member 266 when the cutting device is in the first cutting position of the cutting device.

[0099] In the figures, it is noted that considering the longitudinal axis A, the stroke end stop element 262 is located between the stroke end stop member 266 and the foot pad 224.

[0100] To move the stroke end stop element 262 between its stowed and deployed positions, the first part also includes an actuator 261 that appears to be in the form of a pneumatic jack that enables the stroke end stop element to be moved in a direction of movement B that crosses the longitudinal axis A.
