Description

Technical Field

[0001] This utility model belongs to the technical field of mattress stacking machines, specifically relating to a support and separation device for a mattress stacking machine and a mattress stacking machine. Background Technology

[0002] In the mattress manufacturing industry, there is an existing type of mattress stacker. When the external conveyor belt feeds the mattress into the stacker, the rollers of the stacker's support and separation device also move synchronously along the direction of the external conveyor belt, so that the mattress is completely inside the stacker (supported by the support and separation device). Then, the rollers move in the opposite direction under the action of the chain. Due to the blocking mechanism of the stacker, the mattress is blocked and cannot move. When it loses the support of the support and separation device, the mattress falls under the action of gravity.

[0003] In existing mattress stacking machines, to ensure sufficient friction as the mattress enters the machine, the rollers have a certain roughness and cannot rotate relative to the mattress. The contact surface between the rollers of the support / separation device and the mattress is relatively stationary to prevent slippage and ensure the mattress is fully inserted into the stacking machine. However, in this structure, the rollers can scratch the outer surface of the mattress as they move relative to it. If the rollers and mattress are made rotatable to avoid scratching, the mattress may not fully move onto the support / separation device (when the mattress's center of gravity is on the support / separation device, the friction generated by the external conveyor belt is very small, and the friction provided by the rollers is also very small), or the mattress may move onto the support / separation device but not reach the preset designated position. Summary of the Invention

[0004] This invention addresses the shortcomings of existing mattress stacking machines, which cannot simultaneously ensure the mattress fully enters the machine and avoids damage to its outer surface. It provides a support and separation device for the mattress stacking machine. Through the unidirectional rotation of the rollers, it ensures the mattress fully enters the stacking machine and reaches the desired position, while preventing or reducing scratches on the mattress when the rollers move in the opposite direction. This invention also provides a mattress stacking machine employing this support and separation device.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a support and separation device for a mattress stacker, the support and separation device for the mattress stacker comprising:

[0006] Multiple roller assemblies, each including a roller;

[0007] Transmission components;

[0008] The power unit drives the roller assembly to move back and forth via the transmission unit;

[0009] The rollers of the roller assembly rotate only in one direction when the roller assembly moves in the opposite direction to the mattress entering the mattress stacker.

[0010] This invention relates to a mattress stacker's support and separation device, which comprises multiple roller assemblies. During stacking, the rollers of these assemblies support and separate the mattresses. The roller assemblies move back and forth as a whole, with each roller rotating only in one direction. When the direction of movement of the roller assembly is the same as the direction in which the mattress enters the stacker, the rollers do not rotate, and the friction between the rollers and the mattresses is static friction, thus reliably and completely delivering the mattresses to the desired position in the stacker. During stacking, the power assembly drives the roller assembly to move in the opposite direction to the direction in which the mattresses enter through the transmission assembly. At this time, the rollers can rotate, and the friction between the rollers and the mattresses is rolling friction, effectively avoiding or reducing scratches caused by the rollers to the mattresses. The rollers have a certain degree of roughness.

[0011] As an improvement, the roller assembly includes a spindle fixed to the transmission assembly and a roller that rotates unidirectionally relative to the spindle.

[0012] As an improvement, the roller assembly also includes a one-way bearing, the outer ring of which is fixed to the roller, and the inner ring of which is fixed to the spindle.

[0013] As an improvement, the outer ring of the one-way bearing is fixed to the roller by a set screw, and the inner ring is fixed to the spindle by a flat key.

[0014] As an improvement, the transmission assembly includes a sprocket and a chain, with the spindle fixedly connected to the chain.

[0015] As an improvement, a connecting piece is fixed to the chain, and the spindle is fixed to the connecting piece by an axial screw.

[0016] As an improvement, the chain is arranged in an L-shape, including a horizontal section at the top and a vertical section at the bottom.

[0017] As an improvement, a slot is provided on the spindle, located at the outer axial end of the one-way bearing, and a retaining spring is provided in the slot, which abuts against the inner ring of the one-way bearing.

[0018] As an improvement, the power unit includes a geared motor.

[0019] Mattress stacker crane, the mattress stacker crane comprising:

[0020] frame;

[0021] The separation device is located on the upper part of the frame;

[0022] The lifting mechanism includes a support frame that lifts relative to the frame;

[0023] A blocking mechanism, including a blocking element that switches between an avoidance position and a blocking position;

[0024] The support separation device is the aforementioned support separation device of the mattress stacker.

[0025] The beneficial effects of the support and separation device of the mattress stacker of this utility model are: during the process of the mattress entering the stacker, the roller cannot rotate, and the roller and the mattress move as a whole to ensure that the mattress is delivered to the correct position; when the mattress is stacked, the roller can rotate relative to the mattress to avoid or reduce mattress scratches.

[0026] The mattress stacking machine of this utility model adopts the support and separation device of this utility model and has all the beneficial effects of the support and separation device of this utility model. Attached Figure Description

[0033] The technical solutions of the embodiments of the present invention will be explained and described below. However, the following embodiments are only preferred embodiments of the present invention and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments in the implementation methods without creative effort are all within the protection scope of the present invention.

[0034] See Figures 1 to 7 The mattress stacker's support and separation device according to this utility model embodiment includes:

[0035] Multiple roller assemblies, each including a roller;

[0036] Transmission components;

[0037] The power unit drives the roller assembly to move back and forth via the transmission unit;

[0038] The rollers of the roller assembly rotate only in one direction when the roller assembly moves in the opposite direction to the mattress entering the mattress stacker.

[0039] The mattress stacker of this invention has a support and separation device with multiple roller assemblies. During stacking, the rollers of the roller assembly support the mattress and separate from it. The roller assembly moves back and forth as a whole, and the rollers rotate only in one direction. When the moving direction of the roller assembly is the same as the direction in which the mattress enters the stacker, the roller does not rotate, and the friction between the roller and the mattress is static friction, thus reliably and completely delivering the mattress into the required position in the stacker. When stacking, the power assembly drives the roller assembly to move in the opposite direction of the mattress entry direction through the transmission assembly. At this time, the roller can rotate, and the friction between the roller and the mattress is rolling friction, which effectively avoids or reduces mattress scratches.

[0040] Example 1

[0041] See Figures 1 to 7 The mattress stacking machine of Embodiment 1 of this utility model includes:

[0042] Rack 02;

[0043] The separation device 01 is located on the upper part of the frame 02;

[0044] The lifting mechanism 03 includes a support frame that lifts relative to the frame 02;

[0045] The blocking mechanism 04 includes a blocking element that switches between an avoidance position and a blocking position;

[0046] The supporting separation device 01 includes:

[0047] Multiple roller assemblies 1, each including a roller 11;

[0048] Transmission component 2;

[0049] Power component 3 drives roller assembly 1 to move back and forth via transmission component 2;

[0050] In this process, the roller 11 of the roller assembly 1 rotates only in one direction when the roller assembly 1 moves in the opposite direction to the mattress entering the mattress stacker.

[0051] See Figures 1 to 5In this embodiment, the main working process of the mattress stacker is as follows: First, the external conveyor belt 05 transports the mattress into the stacker. During the operation of the external conveyor belt 05, the support and separation device 01 also works simultaneously (at least for a portion of the time). The speeds of the external conveyor belt 05 and the support and separation device 01 are the same. After the mattress reaches the roller 11 of the support and separation device 01 for a period of time, the mattress separates from the external conveyor belt 05. Driven by the support and separation device 01, the mattress reaches the desired designated position. During this process, the blocking member of the blocking mechanism 04 is in the avoidance position (from...). Figure 1 The state shown becomes Figure 2 (As shown in the diagram); when the mattress is delivered to its position, the blocking component of the blocking mechanism 04 moves to the blocking position, the power component 3 of the support separation device 01 reverses, and the lifting mechanism 03 drives the support frame to rise. After the mattress has moved a short distance, it is blocked by the blocking component and can no longer move. Figure 3 As shown in the diagram, the support frame of the lifting mechanism 03 also rises to the required specified height; the support separation device 01 continues to move, and the roller assembly 1 of the support separation device 01 changes from a horizontal direction to a vertical downward movement, the roller assembly 1 gradually separates from the mattress, and the mattress falls completely onto the support frame of the lifting mechanism 03 under the action of gravity. Figure 4 As shown in the diagram (with some mattresses already on the support frame); the support separation device 01 continues to move until the roller assembly 1 is completely removed from the horizontal position, then the blocking mechanism 04 returns to the avoidance position, the support frame of the lifting mechanism 03 descends, and the mattress stacker reaches its destination. Figure 5 As shown in the diagram, stack the next mattress.

[0052] In this embodiment, since the roller assembly 1 cannot rotate when it moves in the same direction as the mattress feeding direction, a sufficiently large frictional force can be generated between the roller 11 and the mattress, allowing the mattress to move completely from the external conveyor belt 05 onto the roller 11. If the roller assembly 1 can also rotate when it moves in the same direction as the mattress feeding direction, the frictional force between the roller 11 and the mattress is smaller, which may result in the mattress not being able to move completely from the external conveyor belt 05 onto the roller 11.

[0053] In this embodiment, when the roller assembly 1 moves in the opposite direction to the mattress feeding direction, the roller 11 can rotate. This allows the roller 11 to roll relative to the mattress when it is blocked by the blocking member, thus avoiding or reducing the scraping of the mattress by the roller 11. If the roller 11 cannot rotate, although it ensures the mattress can smoothly move from the external conveyor belt 05 onto the roller 11, when the roller assembly 1 moves in the opposite direction to the mattress feeding direction, there is sliding friction between the roller 11 and the mattress, resulting in more severe scraping.

[0054] In this embodiment, the specific structures of the frame 02, lifting mechanism 03, blocking mechanism 04, etc., can be referred to the accompanying drawings and prior art. The lifting mechanism 03 includes a lifting chain assembly, a drive unit, and a support platform disposed between the columns. The drive unit drives the support platform to rise and fall via the lifting chain assembly. The lifting chain assembly includes four axles arranged in a matrix and parallel to each other at the four corners of the frame, as well as large and small ring chains. The large ring chains are wound around the four axles, and the small ring chains are wound around two axles located on the same side of the frame. The drive unit drives the large and small ring chains to run synchronously via the axles and controls the support platform to rise and fall in a horizontal posture. The lifting mechanism includes a counterweight assembly, which includes a counterweight frame and counterweight components disposed on the counterweight frame. The blocking mechanism 04 includes a cylinder that drives the blocking member. The blocking member swings relative to the frame 02. Under the action of the cylinder, the blocking member switches between a clearance position and a blocking position by swinging. The cylinder is located on the outside of the mattress. In the clearance position, the blocking member is positioned above the mattress and horizontally. In the blocking position, the lower end of the blocking member is lower than the upper end of the mattress and vertically. In the blocking position, the blocking member acts as a limit, causing the mattress to drop along a uniform, specific position.

[0055] See Figure 6 and Figure 7 In this embodiment, the roller assembly 1 includes a spindle 12 fixedly connected to the transmission assembly 2 and a roller 11 that rotates unidirectionally relative to the spindle 12.

[0056] In this embodiment, the roller assembly 1 further includes a one-way bearing 13. The outer ring of the one-way bearing 13 is fixedly connected to the roller 11, and the inner ring is fixedly connected to the spindle 12. By using the one-way bearing 13, unidirectional rotation is achieved while maintaining a simple and reliable structure. The one-way bearing 13 can adopt various structural forms such as ramp type, roller type, and wedge type.

[0057] In other embodiments, a ratchet mechanism may also be used, such as mounting a pawl on the spindle 12 and a ratchet on the roller 11, or fixing the roller 11 and the spindle 12 together, rotating the spindle 12 with the transmission assembly 2, mounting a ratchet on the spindle 12, and mounting a pawl on the transmission assembly 2.

[0058] In this embodiment, the outer ring of the one-way bearing 13 is fixed to the roller 11 by the set screw 14, and the inner ring is fixed to the spindle 12 by the flat key 15.

[0059] In this embodiment, the transmission assembly 2 includes sprockets 22 and chains 21, with the spindle 12 fixedly connected to the chain 21. The transmission assembly 2 also includes a mounted bearing 23. The sprockets 22 have at least two sets, namely a driving sprocket set and a driven sprocket set, and there are two chains 21.

[0060] In this embodiment, a connecting piece 16 is fixedly connected to the chain 21, and the spindle 12 is fixedly connected to the connecting piece 16 by an axial screw 17.

[0061] In this embodiment, the chain 21 is L-shaped, comprising an upper horizontal portion 211 and a lower vertical portion 212. This structure is compact and does not occupy horizontal space. In other embodiments, the chain 21 can also be linearly distributed, with the roller 11 moving horizontally in a straight line. In this case, it occupies more horizontal space.

[0062] In this embodiment, in order to achieve the steering of the chain 21, the transmission assembly 2 includes two sets of steering sprockets 22 in addition to the driving sprocket set and the driven sprocket set.

[0063] In this embodiment, a slot is provided on the spindle 12, the slot is located at the outer axial end of the one-way bearing 13, and a retaining spring is provided in the slot, the retaining spring abutting against the inner ring of the one-way bearing 13.

[0064] In this embodiment, the power component 3 includes a geared motor.

[0065] The beneficial effects of the mattress stacker in Embodiment 1 of this utility model are as follows: During the process of the mattress entering the stacker, the roller 11 cannot rotate, and there is static friction between the roller 11 and the mattress, with a large frictional force, which ensures that the mattress is moved from the external conveyor belt 05 onto the roller 11 and that the mattress is delivered to the correct position; When the mattress is stacked, the roller assembly 1 moves in the opposite direction to the direction in which the mattress enters, and the roller 11 can rotate relative to the mattress. There is rolling friction between the roller 11 and the mattress rather than sliding friction, which avoids or reduces the scraping of the mattress by the roller.

[0066] This utility model embodiment also provides a support and separation device 01 for a mattress stacker, the support and separation device 01 including:

[0067] Multiple roller assemblies 1, each including a roller 11;

[0068] Transmission component 2;

[0069] Power component 3 drives roller assembly 1 to move back and forth via transmission component 2;

[0070] In this process, the roller 11 of the roller assembly 1 rotates only in one direction when the roller assembly 1 moves in the opposite direction to the mattress entering the mattress stacker.

[0071] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Those skilled in the art should understand that the present invention includes, but is not limited to, the content described in the above specific embodiments. Any modifications that do not depart from the functional and structural principles of the present invention will be included within the scope of the claims.
