Description

Technical Field

[0001] This utility model relates to a box clamping device. Background Technology

[0002] Product-filled boxes typically consist of a box body and a lid. Most lids are larger than the box body to fit over it, resulting in the lid protruding outwards from the side of the box. Most clamping devices use vertically extending clamping surfaces to grip the sides of the box body, relying on friction between the clamping surfaces and the box body to ensure stability. However, when clamping a box with a lid, the outward protrusion of the lid and the box body means they are not on the same plane, increasing the difficulty of clamping. Furthermore, most box clamping devices only increase the clamping force applied to the box body to improve stability. This method is highly susceptible to deformation of the box body and poses a risk of damaging the products inside. Utility Model Content

[0003] The purpose of this invention is to provide a new box clamping device.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is: a box clamping device, comprising:

[0005] The clamping arm has two sets of clamping arms spaced apart along a first direction. The two sets of clamping arms can be arranged relatively far apart or close together along the first direction. A clamping space for clamping the box is formed between the two sets of clamping arms. The clamping arm has a first side facing the clamping space.

[0006] A clamping member is fixedly connected to the lower part of the clamping arm, and the clamping member extends protruding from the first side into the clamping space;

[0007] A support member is rotatably connected to the clamping arm via a pivot extending along a second direction perpendicular to the first direction. The support member has at least a first state and a second state. In the first state, at least a portion of the support member is located below the clamping space. In the second state, the support member is located on the side of the clamping arm opposite to the clamping space.

[0008] In some embodiments, the housing clamping device includes a fixing member movably disposed on the clamping arm along the first direction, and multiple fixing members are disposed along the second direction; the fixing member has at least a first position and a second position relative to the clamping arm; when in the first position, the fixing member extends into the clamping space; when in the second position, the fixing member retracts from the clamping space; an elastic member is provided between the clamping arm and the fixing member, the elastic member being used to provide the force required to drive the fixing member to move towards the first position.

[0009] In some embodiments, the fastener includes a support portion disposed below the clamping member, the support portion having an upward-facing support surface, and the support portion being located within the clamping space when the fastener is in the first position.

[0010] In some embodiments, the fixing member further includes a limiting portion located on the side of the clamping member away from the clamping space along the first direction, and the supporting portion is fixedly connected to the limiting portion. When the fixing member is in the first position, the limiting portion abuts against the clamping member.

[0011] In some embodiments, the housing clamping device is provided with a positioning mechanism, the positioning mechanism including a positioning element and a sensing component, the positioning element being fixedly connected to the rotating shaft, and the positioning element having a detection port offset from the axis of the rotating shaft; the sensing component includes a transmitting part capable of emitting a signal beam and a receiving part for receiving the signal beam, the transmitting part and the receiving part being spaced apart along the second direction, and at least a portion of the positioning element being located between the transmitting part and the receiving part along the second direction; when the support member is in the first state or in the second state, the detection port is located between the transmitting part and the receiving part; when the support member switches between the first state and the second state, the signal beam is blocked by the positioning element.

[0012] In some embodiments, two detection ports are provided circumferentially along the positioning member, the two detection ports being a first detection port and a second detection port, respectively; the sensing components include two sets of sensing components arranged circumferentially along the positioning member, the two sets of sensing components being a first sensing component and a second sensing component, respectively; when the support member is in the first state, the first detection port is located on the transmission path of the signal beam of the first sensing component; when the support member is in the second state, the second detection port is located on the transmission path of the signal beam of the second sensing component.

[0013] In some embodiments, the positioning element includes two positioning disks fixedly connected, the two positioning disks being arranged at intervals along the second direction, each of the two positioning disks being provided with a detection port, and the positioning disks being located between the transmitting part and the receiving part along the second direction.

[0014] In some embodiments, the support member includes a connecting portion and a supporting portion. The rotating shaft is rotatably connected to the side of the clamping arm away from the clamping space. The connecting portion is fixedly connected to the rotating shaft. The axis of the connecting portion intersects the axis of the supporting portion. When the support member is in the first state, the supporting portion extends in the horizontal direction.

[0015] In some embodiments, the clamping arm includes a plurality of mounting units spaced apart along the second direction, each mounting unit having a plurality of fixing members along the second direction, and each clamping arm having a plurality of supporting members disposed between two adjacent mounting units.

[0016] In some embodiments, the clamping member has an anti-slip protrusion on the side facing the clamping space.

[0017] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art: The box clamping device of this utility model uses a clamping member to clamp and fix the box body of the material box. Since the clamping member extends protruding into the clamping space relative to the first side, it can ensure that when the clamping member clamps the box body, the box lid does not contact the clamping arm, or the box lid just contacts the clamping arm, thereby eliminating the influence of the outwardly protruding box lid on the clamping device. The box clamping device also includes a support member. When the support member is in the first state, the box body located in the clamping space can be supported on the support member, thereby improving the stability of the box clamping. When the clamping device is driven to approach the box and prepare for clamping operation, the support can switch to the second state. In this state, the support is away from the clamping space, allowing the box to enter the clamping space smoothly. At the same time, since the support is located on the side away from the clamping space, the support will not collide with or interfere with the box. Therefore, the two sets of clamping arms only need to open a small distance enough for the box to enter the clamping space. Correspondingly, when clamping the box located in the clamping space, the clamping arms only need to move a small distance. This reduces the stroke required for the clamping arms to move when performing clamping operation. Attached Figure Description

[0032] The technical solution of this utility model will be described in detail below with reference to the accompanying drawings and specific embodiments, so that the advantages and features of this utility model can be more easily understood by those skilled in the art. Obviously, the embodiments described in this application are only a part of the embodiments, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments in this application without creative effort are within the scope of protection of this application.

[0033] See Figure 1 , Figure 2 The illustrated box clamping device includes clamping arms 1, clamping members 2, and supporting members 3. The clamping arms 1 have two sets spaced apart along a first direction, and the two sets of clamping arms 1 can be arranged relatively far apart or close together along the first direction. A clamping space 100 for clamping a material box 200 is formed between the two sets of clamping arms 1, and the two sets of clamping arms 1 are driven relatively close together to clamp the box located within the clamping space 100. The clamping arms 1 have a first side 11 facing the clamping space 100, and the clamping members 2 are fixedly connected to the lower part of the clamping arms 1, extending protruding from the first side 11 into the clamping space 100.

[0034] The material box 200 containing the product has a lid 201 and a body 202. The lid 201 covers the body 202. Typically, the lid 201 is larger than the body 202, causing it to protrude outwards relative to the body 202 on the outer periphery of the material box 200. In this embodiment, the body 202 is clamped by a clamping member 2. Because the clamping member 2 protrudes inwards relative to the clamping arm 1, it prevents the clamping arm 1 from contacting the lid 201 and squeezing and deforming it before the clamping member 2 completes clamping of the body 202. In some preferred embodiments, a gap still exists between the lid 201 and the clamping arm 1 when the clamping member 2 clamps the body 202. Specifically, a gap exists between the outer periphery of the lid 201 and the first side surface 11 when the clamping member 2 clamps the body 202. This configuration ensures that the clamping member 2 securely clamps and fixes the box body 202. At the same time, by leaving a certain contact allowance between the clamping arm 1 and the box cover 201, the clamping device can better adapt to material boxes 200 of different types and different sizes of box covers 201.

[0035] In this embodiment, the support member 3 is rotatably connected to the clamping arm 1 via a rotating shaft 4. The rotating shaft 4 extends along a second direction, which is perpendicular to the first direction. See also [link to relevant documentation] in this embodiment. Figure 1 , Figure 6As shown, both the first and second directions extend horizontally. The support member 3 has at least a first state and a second state. In the first state, at least a portion of the support member 3 is located below the clamping space 100. In this state, the support member 3 can support the bottom of the material box 200 located within the clamping space 100, preventing the material box 200 from falling. In the second state, the support member 3 is away from the clamping space 100. In this state, the clamping device can be driven to approach the material box 200, allowing the material box 200 to enter the clamping space 100. In this embodiment, in the second state, the support member 3 is located on the side of the clamping arm 1 facing away from the clamping space 100. This avoids collisions or interference between the support member 3 and the material box 200 during the process of the clamping device approaching the material box 200. Since the support member 3 does not interfere with the material box 200, when the clamping device approaches the material box 200, the two sets of clamping arms 1 only need to open a small distance, allowing the material box 200 to enter the clamping space 100.

[0036] In this embodiment, the box clamping device further includes a base 10, and two clamping arms 1 are movably disposed on the lower part of the base 10 along a first direction. Specifically, the base 10 is provided with a guide rail extending along the first direction, and the clamping arms 1 are slidably connected to the guide rail, which provides guidance for the movement of the clamping arms 1. In this embodiment, the first side 11 extends vertically. In this embodiment, the rotating shaft 4 is rotatably connected to the side of the clamping arm 1 facing away from the clamping space 100.

[0037] In this embodiment, the box clamping device includes a fixing member 5, which is movably disposed on the clamping arm 1 along a first direction. The fixing member 5 has at least a first position and a second position relative to the clamping arm 1. When in the first position, see [reference needed]. Figure 5 As shown, the fixing member 5 extends into the clamping space 100; when in the second position, see Figure 4 As shown, the fixing member 5 exits the clamping space 100. An elastic member 6 is provided between the clamping arm 1 and the fixing member 5. The elastic member 6 is used to provide the force required to drive the fixing member 5 to move to the first position.

[0038] Some material boxes 200 have slots on their outer periphery for easy handling or fixing. By providing fixing members 5, when clamping the material box 200, the fixing members 5 can be inserted into the slots on the periphery of the material box 200, thereby improving the stability of the clamping. The shape, size, and number of the slots on the periphery vary depending on the type of material box 200. In this embodiment, see... Figure 6 , Figure 12As shown, multiple fasteners 5 are provided along the second direction. By providing multiple fasteners 5 and the fasteners 5 being able to extend and retract relative to the clamping space 100, when clamping the material box 200, the fastener 5 corresponding to the slot position can extend into the slot, and the other fasteners 5 can automatically exit the clamping space 100 under the drive of the side wall of the material box 200.

[0039] In this embodiment, see Figure 12 , Figure 13 As shown, the fixing member 5 includes a supporting part 51, which is disposed below the clamping member 2. The supporting part 51 has an upward-facing support surface 511. When the fixing member 5 is in the first position, the supporting part 51 is located within the clamping space 100. In addition to being able to be inserted into the slot around the material box 200 to improve clamping stability, the fixing member 5 can also abut against the bottom of the material box 200 when clamping the material box 200, so that the fixing member 5 plays the role of supporting the material box 200. The fixing member 5 and the supporting member 3 together support the material box 200, maintain the stability of the material box 200 and prevent the material box 200 from falling.

[0040] In this embodiment, see Figure 4 , Figure 5 As shown, the fixing member 5 also includes a limiting part 52, which is located along the first direction on the side of the clamping member 2 away from the clamping space 100. The supporting part 51 is fixedly connected to the limiting part 52. Specifically, the supporting part 51 is fixedly connected to the side of the limiting part 52 near the clamping space 100. When the fixing member 5 is in the first position, the limiting part 52 abuts against the clamping member 2, limiting the displacement of the fixing member 5 and preventing the fixing member 5 from moving beyond its range.

[0041] In this embodiment, see Figure 5 , Figure 9 As shown, a mounting unit 12 is provided at the lower part of the clamping arm 1. The mounting unit 12 is fixed to the side of the clamping arm 1 facing away from the clamping space 100. The mounting unit 12 has a mounting cavity 121 extending along a first direction. The fixing member 5 is movably disposed in the mounting cavity 121 along the first direction. When the fixing member 5 is in the first position, the supporting part 51 extends out of the mounting cavity 121 and into the clamping space 100. Specifically, the mounting cavity 121 has an opening facing the clamping space 100. Part of the clamping member 2 is positioned above the opening of the mounting cavity 121, and the supporting part 51 can extend out of the mounting cavity 121 from below the clamping member 2. See also Figures 3 to 5 As shown, the elastic element 6 is a spring, which is disposed between the side wall of the mounting cavity 121 and the fixing element 5.

[0042] In this embodiment, the clamping arm 1 includes a plurality of mounting units 12 spaced apart along the second direction. Each mounting unit 12 is provided with a plurality of fixing members 5 along the second direction. A plurality of support members 3 are spaced apart on each set of clamping arms 1. The plurality of support members 3 on each set of clamping arms 1 share the same rotating shaft 4. A drive mechanism is provided on one side of the rotating shaft 4 for driving the rotating shaft 4 to rotate around its own axis. Under the drive of the drive mechanism, the plurality of support members 3 on any set of clamping arms 1 rotate synchronously, thereby synchronously switching between the first state and the second state.

[0043] In this embodiment, see Figure 9 As shown, multiple brackets 13 are provided on the side of the clamping arm 1 away from the clamping space 100. The brackets 13 are arranged between the mounting unit 12 and the clamping arm 1, which on the one hand realizes the fixed connection between the mounting unit 12 and the clamping arm 1, and ensures the stability of the connection between the mounting unit 12 and the clamping arm 1. On the other hand, the rotating shaft 4 is rotatably mounted on the bracket 13. Specifically, some of the brackets 13 are provided with bearings, and the rotating shaft 4 passes through multiple bearings.

[0044] In this embodiment, the support member 3 is disposed between two adjacent mounting units 12. Specifically, see [link to documentation]. Figures 7 to 10 As shown, in two adjacent mounting units 12, each of the two adjacent ends of the two mounting units 12 is provided with a bracket 13. When the support member 3 is in the second state, the support member 3 is housed between the two brackets 13. In this embodiment, the support member 3 includes a connecting part 31 and a supporting part 32. The connecting part 31 is fixedly connected to the rotating shaft 4, and the axis of the connecting part 31 intersects the axis of the supporting part 32. When the support member 3 is in the first state, see... Figure 4 , Figure 5 As shown, the support 32 extends horizontally, thereby providing stable support for the material box 200. When the support 3 is in the second state, see [reference needed]. Figure 7 , Figure 8 As shown, the support 3 can be accommodated between the two brackets 13 as much as possible to avoid interference with the support 3 during the downward clamping of the material box 200.

[0045] In this embodiment, along the vertical direction, when the support member 3 is in the first state, the support surface 511 of the support part 51 is located above the support part 32.

[0046] In this embodiment, the housing clamping device is equipped with a positioning mechanism to ensure that the support member 3 accurately transitions to the first or second state. The positioning mechanism includes a positioning member 71 and a sensing component 72. The positioning member 71 is fixed to the rotating shaft 4 and has a detection port 711 offset from the axis of the rotating shaft 4. The sensing component 72 includes a transmitting part capable of emitting a signal beam and a receiving part for receiving the signal beam. The transmitting part and the receiving part are spaced apart along a second direction, and at least a portion of the positioning member 71 is located between the transmitting part and the receiving part along the second direction. In this embodiment, when the receiving part receives a beam of light from the transmitting part, it can immediately send a signal to the driving mechanism, causing the support member 3 to stop moving. When the support member 3 transitions between the first and second states, the signal beam is blocked by the positioning member 71, and the receiving part does not receive the beam signal, thus the support member 3 continues to rotate. When the support member 3 transitions to either the first or second state, the detection port 711 is located between the transmitting part and the receiving part, and the beam of light emitted by the transmitting part can be received by the receiving part, causing the support member 3 to stop moving.

[0047] In this embodiment, two detection ports 711 are spaced apart circumferentially along the positioning member 71, namely a first detection port and a second detection port. The sensing component 72 includes two sets of sensing components spaced apart circumferentially along the positioning member 71, namely a first sensing component and a second sensing component. The first detection port cooperates with the first sensing component to ensure that the support member 3 can accurately stop in the first state during state transition. The second detection port cooperates with the second sensing component to ensure that the support member 3 can accurately stop in the second state during state transition. Specifically, when the support member 3 is in the first state, the first detection port is located on the transmission path of the signal beam of the first sensing component; when the support member 3 is in the second state, the second detection port is located on the transmission path of the signal beam of the second sensing component.

[0048] See Figure 11 As shown, in this embodiment, the positioning component 71 includes two positioning discs 710 spaced apart along a second direction. Each positioning disc 710 has a first detection port and a second detection port. One positioning disc 710 is located between the transmitter and receiver of the first sensing component along the second direction, and the other positioning disc 710 is located between the transmitter and receiver of the second sensor along the second direction. The two positioning discs 710 are fixedly connected and rotate synchronously under the drive of the rotating shaft 4. In this embodiment, the driving mechanism and the positioning mechanism are located at opposite ends of the rotating shaft 4. Along the second direction, multiple support members 3 are located between the driving mechanism and the positioning mechanism.

[0049] In this embodiment, the clamping member 2 is provided with an anti-slip protrusion 21 on the side facing the clamping space 100, which is used to increase the friction between the clamping member 2 and the side of the material box 200 and improve the stability of clamping.

[0050] In summary, the box clamping device of this embodiment uses clamping member 2 to clamp and fix the box body 202 of the material box 200. Since clamping member 2 protrudes into the clamping space 100 relative to the first side 11, it can ensure that when clamping member 2 clamps the box body 202 of the material box 200, the box cover 201 does not contact the clamping arm 1, or the box cover 201 just contacts the clamping arm 1, thereby eliminating the influence of the outwardly protruding box cover 201 on the clamping device. The box clamping device also includes a support member 3. When the support member 3 is in the first state, the box body 202 located in the clamping space 100 can be supported on the support member 3, thereby improving the stability of box clamping. When the clamping device is driven to approach the housing 202 and is ready to perform a clamping operation, the support member 3 can switch to the second state. In this state, the support member 3 is away from the clamping space 100, so that the housing 202 can smoothly enter the clamping space 100. At the same time, since the support member 3 is located on the side away from the clamping space 100, the support member 3 will not collide with or interfere with the housing 202. Therefore, the two sets of clamping arms 1 only need to open a small distance enough for the housing 202 to enter the clamping space 100. Correspondingly, when clamping the housing 202 located in the clamping space 100, the clamping arm 1 only needs to move a small distance. This can reduce the stroke required for the clamping arm 1 to move when performing the clamping operation.

They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
