Description

Technical Field

[0001] The invention relates to the technical field of suspension chain transmission equipment, in particular to an intelligent suspension chain transmission equipment for transporting a compressed sofa. Background Art

[0002] The accumulation type suspension conveyor is a commonly used conveying equipment in the field of suspension chain drive transportation. Users can reasonably plan its process route according to their needs, so that it can transport items to the designated location along the predetermined route, stay at the location for a short time for processing, and then transport them to the next workshop, thus realizing the continuous transportation of items on fixed routes within the same workshop, between different workshops on the same floor, and between different floors.

[0003] A compressed sofa is a piece of furniture that is compressed through a special process for easy transportation and storage. Specifically, the sofa is first placed in a plastic bag with high barrier and tensile strength, then the sofa is flattened by equipment and the air inside the bag is squeezed out, and finally the plastic bag is heat-melted and sealed. After the sofa is compressed and sealed, it needs to be transported to a designated workshop via an accumulation-type overhead conveyor and stays in the workshop for a short time. At this time, workers will print brand information and other logos on the surface of the compressed sofa bag.

[0004] The accumulation type overhead conveyor mainly includes a front trolley and a rear trolley, and is used in conjunction with a stopper and a pusher. When the accumulation type overhead conveyor moves to the designated workshop, the stopper will lift the pusher to separate it from the front trolley, and use the stopper to press against the front trolley to make it stop briefly, so as to process the workpiece. However, in this process, the front trolley will collide with the stopper due to inertia, and it is easy to deform after long-term use, and it cannot cooperate with the pusher, resulting in the problem of losing the pusher. In addition, when the front trolley of the accumulation type overhead conveyor at the rear contacts the rear trolley of the accumulation type overhead conveyor at the front that is in a stagnant state, a collision will also occur, thereby aggravating the deformation of the front trolley and making it more likely to lose the pusher.

[0005] Therefore, an intelligent suspension chain transmission device for transporting a compressed sofa is proposed. Summary of the invention

[0006] The purpose of the present invention is to provide an intelligent suspension chain transmission device for transporting compressed sofas, which solves the problem that the front trolley is easily deformed due to collision, thereby losing the push head. The front car component provides a buffer to reduce the impact force it receives, thereby increasing its service life, and cooperates with the rear car component of another group of accumulation cars to achieve engagement and fixation, avoiding it from deviating from the original position after separation from the push head component, ensuring that it can dock normally with the next group of push head components.

[0007] To achieve the above object, the present invention provides the following technical solutions:

[0008] The intelligent suspension chain transmission device for transporting a compressed sofa comprises a track frame, a stopper, a plurality of push head pieces and a plurality of accumulation car groups, each accumulation car group comprises a front trolley, a rear trolley and a sling, and also comprises a front car assembly, a rear car assembly and a connecting assembly, wherein the front car assembly is connected to the front trolley, the rear car assembly is connected to the rear trolley, and the connecting assembly is connected to the front car assembly and the rear car assembly; the stopper is opened to lift the push head piece located above the front accumulation car group to separate it from the front car assembly of the accumulation car group, the rear push head piece drives the rear accumulation car group to move forward, so that the front trolley of the rear accumulation car group approaches the rear trolley of the front accumulation car group, the front car assembly of the rear accumulation car group is plugged and locked with the rear car assembly of the front accumulation car group, and at the same time, the push head piece providing power for the rear accumulation car group is separated from the accumulation car group, the push head piece moves forward to be connected with the front car assembly of the front accumulation car group, and unlocks the rear car assembly through the connecting assembly.

[0009] Through the above scheme, when the front car assembly collides with the stopper or the rear car assembly of another group of accumulation car groups, the front car assembly can provide a buffer force to prevent the front car assembly from being deformed after being hit for a long time, so that it cannot be normally connected with the push head part, and then cause the problem of losing the push head; when the push head part is separated from the front car assembly, the accumulation car group will lose traction and stay in place, and the workers also complete the processing of the workpiece at this stage. In order to ensure the stability of the operation, this scheme can lock the pulley of the front trolley through the front car assembly after the accumulation car group is separated from the push head part to prevent it from deviating from the specified position; when the front car assembly of the rear accumulation car group collides with the rear car assembly of the front accumulation car group, the front end of the front car assembly can provide a certain degree of buffer force, thereby avoiding deformation of the workpiece and ensuring its service life, and at the same time providing thrust for the front accumulation car group to move forward; at the same time, when the front car assembly contacts the rear car assembly, it will be plugged and locked to prevent the front accumulation car group from deviating from its original position due to the collision of the rear accumulation car group.

[0010] Preferably, the front vehicle assembly includes a front mounting frame, a buffer spring and a buffer plate, the front mounting frame is connected to the front vehicle, the buffer spring is connected to the front side of the front mounting frame, and the buffer plate is connected to the buffer spring.

[0011] The front vehicle assembly of the accumulation and release vehicle group is hit by two situations in which the front vehicle assembly of the accumulation and release vehicle group is hit by an external force. One is that the front vehicle assembly of the accumulation and release vehicle group collides with the stopper. In this case, the buffer plate will contact with the stopper, and the buffer force provided by the buffer plate and the buffer spring can prevent the front mounting frame from directly hitting the stopper and deforming. The other situation is that the rear vehicle assembly of the front accumulation and release vehicle group is hit by the front vehicle assembly of the rear accumulation and release vehicle group. In this case, the buffer plate and the buffer spring of the rear accumulation and release vehicle group provide buffer force, thereby reducing the impact force on the front vehicle assembly, avoiding deformation and the phenomenon of losing the push head, and ensuring the use effect of the front vehicle assembly. In addition, in this process, since the front vehicle assembly will be locked when it collides with the rear vehicle assembly, the buffer spring will remain in a compressed state. When the front accumulation and release vehicle group needs to move and its locking area is unlocked, the buffer spring will release the elastic force and push the front accumulation and release vehicle group to move forward, thereby preventing the push head from being damaged by the large reaction force required to drive the stationary accumulation and release vehicle group.

[0012] Preferably, the front mounting frame is in a "7" shape, and an inclined surface is provided on the rear side of the front mounting frame. The front vehicle assembly also includes a top block, a movable plate, a connecting plate and a compression spring. The top block is connected to the front mounting frame, and an inclined surface is provided on the rear side of the top block, and the slope is the same as the slope of the inclined surface of the front mounting frame. The two movable plates are connected to the front mounting frame and are respectively located on the left and right sides of the top block. The connecting plate is connected to the front mounting frame and is arranged at the inner corner of the front mounting frame. The two ends of the compression spring are respectively connected to the connecting plate and the movable plate.

[0013] Through the above scheme, the inclined surface on the rear side of the front mounting frame can cooperate with the push head piece, thereby driving the entire accumulating vehicle group to move. When the push head piece engages with the front mounting frame to drive the accumulating vehicle group to move, the push head piece will squeeze the top block, and the top block is subjected to the reverse thrust provided by the movable plate and the compression spring, so that the top block and the push head piece fit more closely, thereby reducing the risk of losing the push head; in addition, in addition to being used to install the compression spring, the connecting plate is set at the inner corner of the front mounting frame, which can also play the role of a reinforcing rib, thereby further improving the strength of the front mounting frame.

[0014] Preferably, a spring sheet is connected below the movable plate, and a surface of one end of the spring sheet away from the movable plate is made of friction material.

[0015] When the push head is separated from the front mounting frame of the front car assembly, the entire storage car group loses power. If it is not limited, it will easily slide randomly and deviate from the original position. Through the above scheme, when the push head is separated from the top block, under the action of the compression spring, the two movable plates will move to the left and right sides respectively, and drive the spring sheet at the bottom to move toward the position of the pulley of the front trolley, so that the spring sheet squeezes the side wall of the above pulley, and the end of the spring sheet is friction material, which can prevent the trolley from slipping by increasing the friction force.

[0016] Preferably, the connecting assembly includes a roller, a connecting rope and a bracket, the roller is connected to the front trolley, the connecting rope is wound around the roller, one end of the connecting rope is connected to the top block, and the other end is connected to the rear trolley assembly, a plurality of brackets are respectively arranged on the front trolley and the rear trolley, the connecting rope passes through the bracket, and the contact surface between the bracket and the connecting rope is made of flexible material.

[0017] Through the above scheme, since the accumulation and release vehicle group needs to turn in some road conditions, the distance between the front trolley and the rear trolley will vary within a small range, so this scheme uses a flexible connecting rope to connect the front vehicle assembly and the rear vehicle assembly; at the same time, multiple brackets are respectively provided on the front trolley and the rear trolley to support the connecting rope to ensure its tension, avoid falling or entanglement, and ensure its use effect, and the flexible material of the contact surface between the bracket and the connecting rope can slow down the wear rate of the connecting rope, thereby ensuring its service life.

[0018] Preferably, the rear vehicle assembly comprises a rear mounting frame, a cavity is provided inside the rear mounting frame, and the rear end of the upper side of the rear mounting frame is provided with an arc chamfer and is covered with a flexible material.

[0019] Through the above scheme, since the rear mounting frame is needed to lift up the push head member of the rear accumulation vehicle group, an arc chamfer is provided at the rear end of the rear mounting frame to increase the contact area and reduce the contact pressure with the push head member. The setting of the flexible surface material can reduce the probability of deformation after the rear mounting frame and the push head member collide, thereby ensuring their service life.

[0020] Preferably, the front vehicle assembly also includes a fixing plate, which is connected to the front mounting frame, and a card slot is provided on the fixing plate; the rear vehicle assembly also includes a connecting rod, a return spring, a mounting plate, a hinged rod and a card block, the connecting rod is connected to the rear mounting frame, and the end thereof away from the rear mounting frame is connected to the connecting rope, the mounting plate is connected to the connecting rod, the two ends of the return spring are respectively connected to the mounting plate and the rear mounting frame, the card block is slidably connected to the lower side of the rear mounting frame, the two ends of the hinged rod are respectively hingedly connected to the mounting plate and the card block, the rear side of the card block is provided with an inclined surface, and the front side of the fixing plate is provided with an arc chamfer.

[0021] Through the above scheme, when the two groups of accumulation and release vehicles approach each other, the fixed plate of the rear accumulation and release vehicle group will move to the bottom of the rear mounting frame of the front accumulation and release vehicle group. At this time, the arc chamfer at the front end of the fixed plate will cooperate with the inclined surface on the rear side of the card block, thereby squeezing the card block into the cavity inside the rear mounting frame. When the card slot on the fixed plate moves to the card block, the card block is reset and stuck in the card slot under the action of the reset spring. The locking of the rear trolley is achieved through the card block and the card slot, limiting its position and preventing it from slipping.

[0022] Preferably, the length of the card slot in the front-to-back direction is greater than the length of the card block in the front-to-back direction.

[0023] Through the above scheme, when the two groups of accumulation and release vehicles come into contact, a buffer force will be provided by the buffer plate and the buffer spring. That is to say, the rear accumulation and release vehicle group will rebound and move backward a short distance under the action of the buffer spring. Therefore, it is necessary to leave a certain amount of activity margin to avoid affecting the service life of the card block. At the same time, when the fixed plate squeezes the card block, it can also provide a certain degree of buffer force for the contact between the two groups of accumulation and release vehicles.

[0024] Preferably, one end of the connecting rod away from the mounting plate extends to the outside of the rear mounting frame.

[0025] Through the above solution, the connection rope is prevented from being worn out due to friction with the rear mounting frame, thereby ensuring the service life of the connection rope.

[0026] Compared with the prior art, the present invention has the following beneficial effects:

[0027] 1. An intelligent suspension chain transmission device for transporting a compressed sofa of the present invention provides a front vehicle assembly. When the front vehicle assembly collides with a stopper or a rear vehicle assembly of another accumulation vehicle assembly, a buffer plate and a buffer spring at the front end of the front vehicle assembly are used to provide a certain buffer force for the accumulation vehicle assembly, thereby preventing the front vehicle assembly from being deformed after being hit for a long time and being unable to dock with the push head member normally, thereby reducing the probability of the push head being lost and ensuring its use effect. In addition, when the two accumulation vehicle assembly groups are close, the buffer spring of the rear accumulation vehicle assembly will be charged. When the front vehicle is unlocked and is about to move forward again from a stationary state, the buffer spring will release its elastic force and push the front accumulation vehicle assembly through the buffer plate, so that it has a tendency to move forward, thereby preventing the push head member from being damaged by the large reaction force required to drive the stationary accumulation vehicle assembly.

[0028] 2. An intelligent suspension chain transmission device for transporting a compressed sofa of the present invention is provided with a front vehicle assembly and a rear vehicle assembly. When the front vehicle assembly of the rear accumulation vehicle assembly collides with the rear vehicle assembly of the front accumulation vehicle assembly, the fixing plate at the bottom of the front vehicle assembly will move and be plugged into the bottom of the rear vehicle assembly. At this time, the card slot on the fixing plate will cooperate with the card block under the rear mounting frame to realize the card connection and fixation of the two accumulation vehicle assembly groups. By setting the length of the card slot, a certain amount of movable space is reserved for the card block, thereby ensuring the service life of the card block and limiting the position of the two accumulation vehicle assembly groups at the same time, thereby preventing them from sliding arbitrarily and deviating from the existing position.

[0029] 3. The intelligent suspension chain transmission device for transporting a compressed sofa of the present invention is provided with a top block and a spring sheet. When the push head part is engaged with the front mounting frame, the top block will be squeezed, and the top block will provide a reverse thrust for the push head part under the action of the compression spring, so that the two can fit more closely and reduce the risk of losing the push head. When the push head part is separated from it, the movable plate will squeeze the pulley of the front trolley with the spring sheet under the action of the compression spring, and increase the friction of the movement of the front trolley through the friction material at its end, thereby limiting the displacement of the front trolley and preventing it from deviating from the existing position.

The connecting assembly 9 is connected to the front trolley assembly 7 and the rear trolley assembly 8; the front trolley assembly 7 includes a front mounting frame 701, a buffer spring 702 and a buffer plate 703. The front mounting frame 701 is connected to the front trolley 4, and the buffer spring 702 is connected to the front side of the front mounting frame 701. The buffer plate 703 is connected to the buffer spring 702. When the front mounting frame 701 of the front trolley assembly 7 is about to be hit, a certain degree of buffering force will be provided by the buffer spring 702 and the buffer plate 703, thereby avoiding the deformation of the front mounting frame 701 after frequent impact, and thus failing to dock with the push head member 3 normally, resulting in the phenomenon of losing the push head, thereby ensuring the use effect of the front trolley assembly 7.

[0042] As an embodiment of the present invention, refer to Figure 4The rear side of the front mounting frame 701 is provided with an inclined surface, which can cooperate with the end of the push head member 3, so that the push head member 3 is used to drive the entire accumulation vehicle group to move. The front vehicle assembly 7 also includes a top block 704, a movable plate 705, a connecting plate 706 and a compression spring 707. The top block 704 is slidably connected to the front mounting frame 701. The rear side of the top block 704 is provided with an inclined surface and the slope is the same as the slope of the inclined surface of the front mounting frame 701. When the push head member 3 is used, the front vehicle assembly 7 also includes a top block 704, a movable plate 705, a connecting plate 706 and a compression spring 707. The top block 704 is slidably connected to the front mounting frame 701.

At this time, the inclined surface of the top block 704 can also cooperate with the end of the push head piece 3. When the push head piece 3 is engaged with the front mounting frame 701 to drive the accumulation vehicle group to move, the push head piece 3 will squeeze the top block 704, and the top block 704 is subjected to the reverse thrust provided by the movable plate 705 and the compression spring 707, so that the top block 704 and the push head piece 3 are more closely fitted, thereby reducing the risk of losing the push head.

[0043] The two movable plates 705 are connected to the front mounting frame 701 and are respectively located at the left and right sides of the top block 704. A spring sheet 708 is connected under the movable plate 705. When the push head member 3 is separated from the top block 704, under the action of the compression spring 707, the movable plate 705 will drive the spring sheet 708 at its bottom to move toward the position of the pulley of the front trolley 4, so that the spring sheet 708 squeezes the side wall of the above-mentioned pulley. The surface of the end of the spring sheet 708 away from the movable plate 705 is coated with rubber material, which can provide a strong friction force, thereby preventing the trolley from sliding at will by increasing the friction force; the connecting plate 706 is connected to the front mounting frame 701 and is arranged at the inner corner of the front mounting frame 701. The two ends of the compression spring 707 are respectively connected to the connecting plate 706 and the movable plate 705. In addition to being used to install the compression spring 707, the connecting plate 706 is arranged at the inner corner of the front mounting frame 701, which can also play the role of a reinforcing rib, thereby further improving the strength of the front mounting frame 701.

[0044] As an embodiment of the present invention, refer to Figure 2 and Figure 5 The connecting component 9 includes a roller 901, a connecting rope 902 and a bracket 903. The roller 901 is rotatably connected to the front trolley 4. The connecting rope 902 is wound around the roller 901 and tightened. One end of the connecting rope 902 is connected to the lower side of the top block 704, and the other end is connected to the rear trolley component 8. A plurality of brackets 903 are respectively arranged on the front trolley 4 and the rear trolley 5. The connecting rope 902 passes through the bracket 903 to support the connecting rope 902, ensure its tension, avoid falling or winding, and ensure its use effect. The contact surface between the bracket 903 and the connecting rope 902 is made of flexible material, which can slow down the wear rate of the connecting rope 902, thereby ensuring its service life.

[0045] As an embodiment of the present invention, refer to Figure 6 and Figure 7 The rear vehicle assembly 8 includes a rear mounting frame 801, and the rear end of the upper side of the rear mounting frame 801 is provided with an arc chamfer to increase the contact area and reduce the contact pressure with the push head member 3. The arc chamfer is coated with a flexible material, which can provide a certain degree of buffering force to reduce the probability of deformation after the rear mounting frame 801 and the push head member 3 collide, thereby ensuring its service life.

[0046] The front vehicle assembly 7 also includes a fixing plate 709, the front side of which is provided with an arc chamfer, the fixing plate 709 is connected to the front mounting frame 701, a card slot 7010 is provided on the fixing plate 709, the length of the card slot 7010 in the front-to-back direction is greater than the length of the card block 806 in the front-to-back direction, and by setting the length of the card slot 7010, a certain amount of activity space is left for the card block 806, so as to ensure the service life of the card block 806 while limiting the position of the two groups of accumulated vehicle groups, thereby preventing them from sliding arbitrarily and deviating from the existing position; the rear vehicle assembly 8 also includes a connecting rod 802, a return spring 803, a mounting plate 804, a hinge rod 805 and a card block 806, the card block 806 is slidably connected to the lower side of the rear mounting frame 801, and the rear side of the card block 806 is provided with an inclined surface, when the card block 806 and the card slot 7010 are close to each other, the arc chamfer at the front end of the fixing plate 709 will cooperate with the inclined surface at the rear side of the card block 806, so as to prevent the card block 806 from sliding and deviating from the existing position. The block 806 is squeezed into the cavity inside the rear mounting frame 801. When the slot 7010 on the fixing plate 709 moves to the block 806, the block 806 is reset and stuck in the slot 7010 under the action of the reset spring 803. The block 806 and the slot 7010 are connected to lock the rear trolley, limit its position and prevent it from slipping. The connecting rod 802 is connected to the rear mounting frame 801, and its end away from the rear mounting frame 801 is connected to the connecting rod 802. The connecting rod 802 is connected with the rear mounting frame 801 by a rope 902, and one end of the connecting rod 802 away from the mounting plate 804 extends to the outside of the rear mounting frame 801, thereby avoiding the friction and wear of the connecting rope 902 and the rear mounting frame 801, thereby ensuring the service life of the connecting rope 902. The mounting plate 804 is fixed to the connecting rod 802, and the two ends of the return spring 803 are respectively connected to the mounting plate 804 and the rear mounting frame 801, and the two ends of the hinged rod 805 are respectively hingedly connected to the mounting plate 804 and the block 806.

[0047] The specific working principle is as follows: during the normal driving stage of the accumulation vehicle group, the end of the push head member 3 engages with the front mounting frame 701 of the front vehicle assembly 7, thereby dragging the entire accumulation vehicle group forward. When it moves to the specified position, the stopper 2 is controlled to open by electronic control. At this time, the stopper 2 will block the forward path of the accumulation vehicle group. When the accumulation vehicle group approaches the stopper 2, the push head member 3 will first be lifted by the stopper 2 to separate it from the front mounting frame 701. Secondly, the accumulation vehicle group will be prevented from continuing to move forward due to inertia, limiting its position. When the push head member 3 is separated from it, the accumulation vehicle group will lose traction and stay in place. The workers also complete the processing of the workpiece at this stage; when the push head member 3 is separated from the front mounting frame 701, it continues to move forward.

[0048] When the push head member 3 is separated from the front mounting frame 701, the movable plate 705 and the compression spring 707 lose the squeezing force of the top block 704. Therefore, under the action of the compression spring 707, the two movable plates 705 will move to the left and right sides respectively, thereby driving the spring sheet 708 at the bottom thereof to approach the pulley of the front trolley 4, and squeezing the side wall of the pulley through the spring sheet 708. Since the end of the spring sheet 708 close to the pulley is friction material, the movement of the pulley is limited by increasing the friction force, thereby restricting the entire stacking vehicle group in place, making it convenient for the work to carry out subsequent processing of the workpiece.

[0049] When the front accumulation vehicle group stops moving, the other accumulation vehicle group behind it continues to move forward under the action of the push head member 3. When the two accumulation vehicle groups come into contact, the rear mounting frame 801 of the front accumulation vehicle group (hereinafter referred to as the front vehicle) will first come into contact with the buffer plate 703 of the rear accumulation vehicle group (hereinafter referred to as the rear vehicle), and the buffer spring 702 will reduce the impact force to be received, thereby avoiding the problem that the front mounting frame 701 cannot be properly docked with the push head member 3 due to deformation after multiple impacts;

[0050] The push head member 3 of the rear vehicle will also separate from the front mounting frame 701 of the rear vehicle during the above process. Specifically, the mounting frame of the front vehicle will contact the protruding side wall of the push head member 3 of the rear vehicle, so that the push head member 3 is tilted to a certain height, thereby causing the push head member 3 of the rear vehicle to separate from the front mounting frame 701 of the rear vehicle. When the push head member 3 of the rear vehicle is separated from the rear vehicle, the rear vehicle stays behind the front vehicle, while the push head member 3 continues to move forward.

[0051] During the docking process between the rear vehicle and the front vehicle, the rear vehicle will be locked through the cooperation between the block 806 and the slot 7010 to prevent it from deviating from the existing position; specifically, during the process that the fixed plate 709 of the rear vehicle approaches the block 806, the chamfer at the front end of the fixed plate 709 of the rear vehicle will cooperate with the inclined surface of the block 806 to squeeze the block 806 into the internal cavity of the rear mounting frame 801, and when the slot 7010 on the fixed plate 709 moves to the block 806, the block 806 is reset and stuck in the slot 7010 under the action of the reset spring 803, and the locking of the rear vehicle is achieved through the engagement between the block 806 and the slot 7010, thereby limiting its position and preventing it from slipping.

[0052] As mentioned above, when the rear car docks with the front car, the push head member 3 of the rear car will separate from the rear car and continue to move forward. Therefore, when it moves to the front mounting frame 701 of the front car, it will engage with the front mounting frame 701 of the front car. In this process, the lock of the spring sheet 708 on the pulley of the front car 4 will be released first, and the lock of the connection between the rear car and the front car will also be released. When all are unlocked, the push head member 3 will drive the front car to continue moving forward;

[0053] Specifically, when the push head member 3 is engaged with the front mounting frame 701, the top block 704 is pushed to move and squeeze the movable plate 705, so that the movable plate 705 contracts inward, and then the spring sheet 708 gradually moves away from the pulley of the front trolley 4, thereby releasing its lock and enabling it to move normally;

[0054] At the same time, when the top block 704 is squeezed and moved by the push head member 3, the connecting rod 802 will be pulled forward through the connecting rope 902, thereby driving the card block 806 to shrink into the inner cavity of the rear mounting frame 801 through the mounting plate 804 and the hinge rod 805, thereby releasing the cooperation between the card block 806 and the card slot 7010; when all locks are unlocked, the buffer spring 702 of the rear vehicle, which is in a compressed state due to the squeezing of the front vehicle, will release the elastic force and push the front vehicle forward through the buffer plate 703, so that it has a tendency to move forward.

[0055] Finally, the electronically controlled drive stopper 2 is closed, and then the push head member 3 drives the front vehicle to continue to move forward.

[0056] Before the rear vehicle arrives, the stopper 2 is opened by electronic control, and then the above steps are repeated.

[0057] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
