[Solution] The adsorption moving unit 10 is provided with a one-sided auxiliary adsorbent 13 that can contact the main adsorbent 11 at a position separated to the rear and intersecting the left-right direction for the left adsorption group of the left and right adsorption groups. When the multiple adsorbents 11 and 13 are brought into contact with the upper surface of the plate material and raised by a certain amount, the plate material, when viewed from the front, will be curved and bent so that the center is positioned downwards and both outer sides are positioned upwards. When viewed from the left, the one-sided auxiliary adsorbent 13 positioned to the rear will have moved upwards above the main adsorbent 11, and the plate material will be curved and bent so that only the rear side is positioned upwards and the front portion is approximately horizontal.

Description

Technical Field

[0001] The present invention relates to a plate moving device capable of moving a plate material before processing to a preparation position for processing.

Background Art

[0002] Conventionally, as a construction method for manufacturing buildings such as houses, a method using precut processing is known. The precut processing can be used not only for rod-shaped parts (products) such as columns and beams, but also for various plate materials such as floor boards and wall boards for houses, and heat insulating materials installed on floors and walls. A processing machine (plate material processing machine) capable of processing plate materials can be configured to include a device (plate material moving device) that moves from a standby position where a large number of plate materials are stacked before processing, lifts only the topmost one, and moves it to a preparation position for performing cutting processing or cutting.

[0003] As the plate material moving device, there is one configured such that an adsorption moving unit capable of lifting and moving the plate material using suction force can move in the vertical direction side and the horizontal direction side. The adsorption moving unit is provided with a plurality of adsorbing bodies, moves the adsorbing bodies so as to contact the upper surface of the topmost first plate material, and moves the adsorbing bodies upward while adsorbing the plate material by the suction force to lift and move the plate material. At this time, in order to prevent the suction force from acting on the second plate material from the top and a plurality of plate materials from being lifted simultaneously, a method has been proposed in which the first plate material is curved and bent, and air is allowed to enter from the outer peripheral portion with respect to the contact surface between the plate materials to separate the plate materials. As a method of bending the plate material to separate the plate materials, as shown in FIG. 4, a method using two main adsorbing bodies 11 located on the central side of the plate material and auxiliary adsorbing bodies 12 that move above the main adsorbing bodies 11 on both outer sides of the main adsorbing bodies 11 to bend the plate material is known (for example, see Patent Document 1).

[0005] However, while it is preferable to configure a single plate moving device to be able to move plates of different materials or thicknesses, the ease with which plates flex and the degree of air permeability can vary greatly depending on the material, thickness, and size of the plates. Furthermore, in the suction moving unit shown in Figure 4, small plates that do not reach the area where the auxiliary suction body 12 is located cannot be flexed using the auxiliary suction body 12, and therefore cannot be separated by flexing the plates. As a result, in a plate moving device that utilizes suction force, there is a problem that it may be difficult to separate and remove only the top plate from the second plate by utilizing the flexural deformation of the plates.

[0006] The present invention was made to solve the above-mentioned problems, and aims to provide a sheet material moving device that can suitably lift and move the first sheet material located at the top of a waiting position where many sheet materials are stacked. [Means for solving the problem]

[0007] To achieve this objective, the plate material moving device described in claim 1 is A sheet metal moving device is configured such that a suction-assisted moving unit, which is capable of lifting and moving sheet metal using suction force, moves vertically and horizontally, thereby enabling the movement of sheet metal from a waiting position where multiple sheet metals are stacked to a preparation position for processing. The aforementioned adsorption transfer unit is Multiple adsorbents that can come into contact with a plate material and can attract the plate material by suction force, thereby enabling the plate material to be suspended, The system comprises a frame member that integrates the multiple adsorbents, As the plurality of adsorbents, Two main adsorbents are provided at positions spaced apart on both sides along a predetermined alignment direction with respect to a predetermined reference position, The system includes a one-sided auxiliary adsorbent provided at a position spaced apart on the intersecting side, which intersects the predetermined alignment direction with respect to one of the two main adsorbents, The aforementioned auxiliary adsorbent on one side is configured to be movable, including a range of motion that allows it to move by a predetermined amount from a height position approximately the same as that of the main adsorbent, to a position above that approximately same height.

[0008] According to the plate material moving device described in claim 1, when moving a plate material from a standby position to a processing preparation position, the suction moving unit is moved above the standby position, and then the multiple suction bodies are brought into contact with the upper surface of the plate material located at the top of the standby position and suction is performed. The timing at which the multiple suction bodies suction the plate material may all be the same, or the timing may be different.

[0009] When the main adsorbent and the auxiliary adsorbent on one side adsorb to the plate material, the auxiliary adsorbent on one side moves above the main adsorbent, causing the plate material to bend (deform). When the plate material bends, a gap is more likely to form between the top plate (the first plate) and the second plate below it in a stack of multiple plates, causing the top plate to separate from the subsequent plates.

[0010] Here, the auxiliary adsorbent on one side is positioned spaced apart from one of the two main adsorbents, in the direction of intersection that intersects the direction of alignment. Therefore, when the plate is lifted with its center as the reference position, the plate will bend asymmetrically in multiple directions, including the length direction and the width direction (direction perpendicular to the length direction). Thus, when the first plate is lifted by applying an attractive force, the deformation of the plate becomes irregular, making it easier to create areas where air can easily enter.

[0011] The plate material moving device according to claim 2 is the plate material moving device according to claim 1, A pressing force applying means is provided on the reference position side with respect to the main adsorbent, and is capable of contacting the upper surface of the plate material and applying a downward pressing force, The system includes a switching means that can switch between an operating state in which pressing force can be applied by the pressing force applying means and a non-operating state in which no pressing force is applied.

[0012] The plate material moving device according to claim 3 is the plate material moving device according to claim 1 or 2, The main adsorbent is supported by the frame member via a tilting mechanism that allows it to tilt in the direction of a predetermined alignment and in the direction opposite to that predetermined alignment, and is configured to be difficult or impossible to tilt in the direction of the intersection and in the direction opposite to that intersection compared to tilting in the direction of the predetermined alignment and in the direction opposite to that predetermined alignment.

[0013] Furthermore, the sheet material moving device described in claims 1 to 3 may be configured as a device including a processing device (for example, a sheet material processing machine), or as a device that does not include a processing device. [Effects of the Invention]

[0014] According to the plate material moving device of the present invention, by lifting the plate material using multiple adsorbents, including a main adsorbent and one-sided auxiliary adsorbents, a gap is easily created between the topmost plate and the second plate below it, allowing air to easily enter through this gap. Therefore, it is possible to separate and lift only the topmost plate from a waiting position where many plates are stacked and move it to a preparation position. [Brief explanation of the drawing]

Embodiments for Carrying Out the Invention

[0016] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a diagram showing the configuration of the adsorption moving unit 10. FIG. 1(A) is a perspective view seen from the front side, and FIG. 1(B) is a plan view.

[0017] The adsorption moving unit 10 is a device that can be used as a part of a plate moving device for moving a plate in a plate processing machine. When moving a plate (raw material) before processing from a standby position to a preparation position, the plate can be lifted using a suction force. The plate processing machine can be configured to include a plate moving device and a processing device. The processing device can be configured to use a thin plate-shaped cutter that can be cut by movement as a tool for cutting (dividing) the plate. Instead of this, or in addition to this, it can be configured to include a circular saw, a router, etc. that can perform cutting operations by rotation.

[0018] Examples of the plates cut by the plate processing machine include plywood and fiber-based resin plates that can be used as floor boards and wall boards, and foam-based resin plates that can be used as heat insulation materials. Among these various plates, there are plates that are made of high-strength and hard materials and are air-permeable. For example, as a fiber-based resin plate, there is a medium-density fiberboard (MDF) as a wood product obtained by bonding wood fibers with an adhesive and processing them into a plate shape. For this type of plate, it is difficult to separate and lift only the topmost plate by utilizing the bending deformation of the plates from a standby position where a large number of plates are stacked. That is, in plates set with various materials and thicknesses, a situation where it is difficult to separate and lift the plates can occur.

[0019] In contrast, the suction transfer unit 10 is configured to utilize three types of adsorbent bodies 11 to 13, and also to utilize the pressing force provided by the pressing force application mechanism 21. By configuring a plate material moving device using the suction transfer unit 10 with these distinctive features, it becomes possible to easily separate and lift individual plates of various types. Below, the distinctive features of the suction transfer unit 10 will be described, followed by a description of the operation of lifting the plates.

[0020] As shown in Figure 1(A), the suction moving unit 10 is constructed by integrating three types of suction bodies 11 to 13 with a frame member 14. The suction moving unit 10 has a mounting part 15 that can be attached to a moving mechanism, and a suspended crane mechanism or the head part of an articulated robot can be connected to the upper side of the mounting part 15 to configure a sheet material moving device. As a result, the suction moving unit 10 can be configured to move freely in any of the left-right direction (±X direction), front-back direction (±Y direction), and up-down direction (±Z direction). The sheet material processing machine is equipped with a control device that uses a computer to control the processing operations of the sheet material processing machine, and various controls can be performed by the control device, such as the movement of the suction moving unit 10, the on / off switching of the suction of the suction bodies 11 to 13, and the operation of the pressing body 22 by the pressing force applying mechanism 21.

[0021] The adsorbent bodies 11-13 can be composed of suction pads that can come into contact with the plate material and adsorb the plate material by suction force, thereby suspending the plate material. A blower (suction device) is connected to the internal space of the suction pad through a pipe 17, and by operating the suction device, the internal space can be made into a negative pressure, thereby generating suction force.

[0022] The three types of adsorbents 11-13 can be classified into a main adsorbent 11 and two auxiliary adsorbents, an outer auxiliary adsorbent 12 and a one-sided auxiliary adsorbent 13. Although all three types of adsorbents 11-13 may be composed of the same adsorption pad, the example given is that the main adsorbent 11, located in the center, is larger and has greater suction force (adsorption force) than the other outer auxiliary adsorbents 12 and one-sided auxiliary adsorbents 13. Furthermore, the main adsorbent 11 is designed to always generate suction force when lifting the plate material, while the outer auxiliary adsorbents 12 and one-sided auxiliary adsorbents 13 can be configured to allow switching between generating suction force or not generating suction force when lifting the plate material.

[0023] The main adsorbent bodies 11 are arranged so as to be spaced apart to the left and right with respect to a reference position in the horizontal direction. The reference position is a position that allows the plate material to be moved stably by using it so that the central part of the plate material is located there, and in the adsorption movement unit 10, it corresponds to the center between the two main adsorbent bodies 11, and the pressing force applying mechanism 21 (pressing body 22) is installed at this reference position.

[0024] The main suction body 11 is supported so as to be suspended by the frame member 14, and is configured to move a certain amount (for example, approximately 5 cm) upward from its normal vertical position shown in Figure 1(B) by a downward pressing force. Furthermore, the main suction body 11 is configured to tilt so as to be able to make close contact with the deformed surface of the plate when the plate material is deformed so that it becomes convex downward when viewed from the front. Specifically, as shown in Figure 1(A), the tilting mechanism is supported by the frame member 14 via two ball joints 16 that are spaced apart front to back, allowing the lower surface portion to tilt freely from a state where it faces downward to the lower left or lower right, but not to the front or rear.

[0025] Furthermore, the tilting mechanism is not limited to the ball joint 16; other mechanisms may also be used. Also, it is not necessary to configure the support portion of the main suction body 11 so that it can tilt only in a specific direction (the left-right direction in Figure 1(B)); it may be configured to tilt forward or backward as well. However, it is preferable to make the ease of tilting different in the front-back direction and the left-right direction, as this makes the way in which the suction force acts on the plate material irregular, making it easier to separate the plate material.

[0026] The outer auxiliary adsorbent 12 is located further from the reference position than the main adsorbent 11, and is positioned further apart to the left and right of the position where the main adsorbent 11 is installed. The outer auxiliary adsorbent 12 is supported by the frame member 14 in the normal vertical position shown in Figure 1(B) via a bellows-shaped cylindrical body, and is configured to move upward by a certain amount (for example, 10 cm) when the internal space is pulled by negative pressure while the plate material is in contact with the lower surface, causing the cylindrical portion to contract. As a result, when the plate material is lifted, the outer auxiliary adsorbent 12s on both the left and right sides can be positioned above the two main adsorbent 11s located on the inside when viewed from the front side as shown in Figure 1(B), causing the plate material to be curved and deflected so that it is convex downwards.

[0027] Furthermore, the outer auxiliary suction body 12 is supported by the frame member 14 via a ball joint (not shown) and is configured to be tiltable forward, backward, and left and right. This allows the suction force to be applied efficiently to the curved upper surface of the plate material even when the plate material deforms when an suction force (adsorption force) is applied to it, making it easier to curve the plate material.

[0028] The combination of the main adsorbent 11 and the outer auxiliary adsorbent 12 is illustrated in the example where a first adsorption group is provided on the first direction side (right side, +X direction side) with respect to the reference position, and a second adsorption group is provided on the second direction side (left side, -X direction side) opposite to the first direction side, and a one-sided auxiliary adsorbent 13 is provided on the side where the second adsorption group is located. The one-sided auxiliary adsorbent 13 can also be provided at a different location, such as on the side where the first adsorption group is located, but it is preferable to configure the one-sided auxiliary adsorbent 13 to be provided on the side where the processing preparation position is located relative to the standby position, as this makes it easier to transport the sheet material to the standby position.

[0029] The one-sided auxiliary adsorbent 13 can have the same configuration as the outer auxiliary adsorbent 12, and is positioned in the normal vertical position shown in Figure 1(B) via a bellows-shaped cylindrical body. When the plate material is in contact with the lower surface, the internal space is pulled by negative pressure, causing the cylindrical portion to contract and move upward by a certain amount. The one-sided auxiliary adsorbent 13 is provided at a location further from the reference position (the installation position of the pressing body 22) than the main adsorbent 11, and is installed at a position spaced rearward from one of the main adsorbent 11s. That is, the one-sided auxiliary adsorbent 13 is provided on one side (left side) of the positions spaced apart on both sides in the left-right direction relative to the reference position of the two main adsorbent 11, and on one side (rearward side) in the front-back direction that intersects the direction of alignment.

[0030] Here, the outer auxiliary adsorbent 12 and the one-sided auxiliary adsorbent 13 are configured to be movable relative to the main adsorbent 11, including a movement range that allows for movement by a predetermined amount above the approximately same height position as the normal position. Furthermore, the installation position of the one-sided auxiliary adsorbent 13 is on a side different from the left-right direction where the outer auxiliary adsorbent 12 is located relative to the main adsorbent 11, and is set on the rear side that intersects the left-right direction. As a result, when the plate material is lifted using the suction force, the deformation can be such that the outer auxiliary adsorbent 12 causes both the left and right sides to curve upward when viewed from the front, and the one-sided auxiliary adsorbent 13 causes only the left rear corner of the plate material to be lifted higher than the others.

[0031] The suction movement unit 10 is provided with a pressing force application mechanism 21 on the central side (reference position side) relative to the main suction body 11, which can contact the upper surface of the plate material and apply a downward pressing force. The pressing force application mechanism 21 can be configured, for example, with a pressing body 22 that forms a pressing surface and a pneumatic cylinder that moves the pressing body 22 up and down. By controlling the control valve of the pneumatic cylinder with a control device, it is possible to switch between an operating state in which a pressing force can be applied to the plate material and a non-operating state in which no pressing force is applied.

[0032] The lower surface of the pressing body 22 can be set to be above the lower surface of the main suction body 11 in the normal position when not in operation (for example, 15 mm above), and below the lower surface of the main suction body 11 in operation (for example, 10 mm below). This makes it possible to apply pressing force to the upper surface of a plate material that has not deformed much using the pressing body 22, making it easier to separate only one plate at a time.

[0033] The suction transfer unit 10 is equipped with a switching operation unit 31 that switches the operating state of the outer auxiliary adsorbent 12, the one-sided auxiliary adsorbent 13, and the pressing force application mechanism 21. The switching operation unit 31 can be provided on the suction transfer unit 10 itself, or it can be provided together with other operation units in the control device. For example, the switching operation unit 31 can be configured using a switching operation valve 32 that switches the opening and closing of an on-off valve that generates suction force, and it can also be configured to operate a device such as an electromagnetic valve by a mechanical switch that is integrally installed in the operation part of the control device.

[0034] Furthermore, the operation target of the switching operation unit 31 can also include a cycle stop operation. For example, when moving a plate material that the operator thinks might be picked up by two plates, if the cycle stop is turned on, the suction moving unit 10 will temporarily stop operating when it picks up the plate material and raises to that position. The operator can then visually check the raising status of the plate material, and if the second plate material has been lifted, the operator can peel off the second plate material by hand, and then resume operation by pressing a restart switch separate from the cycle stop switch.

[0035] The main suction body 11 can be set to transport small sheet materials located within the 1820mm length dimension (for example, the sheet material shown by the dashed line in Figure 1(A)) in order to facilitate the transport of sheet materials with a standard length of approximately 1820mm and a width of approximately 910mm, which are commonly used as sheet materials. The example shown also illustrates the case where the one-sided auxiliary suction body 13 is set within the standard length range. The outer auxiliary suction body 12 can be used to lift large sheet materials that are longer than 1820mm, and can be switched on or off depending on the length of the sheet material.

[0036] The suction moving unit 10 is equipped with a contact sensor device 41 and a distance measuring sensor device 42. The contact sensor device 41 includes a contact body 43 that moves up and down in a manner that allows detection of contact with the upper surface of the plate material, and is configured to detect whether or not it is in contact with the upper surface of the plate material by detecting the vertical position of the contact body 43. The distance measuring sensor device 42 is a non-contact type and is configured to detect when the upper surface of the plate material located below approaches within a certain range (for example, within 50 cm). These sensor devices 41 and 42 are connected to a control device and can be used to control the movement and suction operation of the suction moving unit 10.

[0037] Next, referring to Figures 2 and 3, the operation of lifting the first sheet metal located at the top of a stack of small sheet metals from a waiting position using the suction moving unit 10 will be described. Figure 2 is an example of the operation of lifting a sheet metal using the pressing force applying mechanism 21. When moving a sheet metal from the waiting position to the processing preparation position, the suction moving unit 10 is moved to the upper side of the waiting position, and then, as shown in Figure 2(A), the multiple suction bodies 11 to 13 are brought into contact with the sheet metal located at the top of the waiting position. At this time, the outer auxiliary suction body 12 is set not to operate because it is located outside the size range of the sheet metal, and it is preferable to move the sheet metal using two types of suction bodies 11 and 13. The timing at which the two types of suction bodies 11 and 13 adsorb the sheet metal may all be the same, and the timing may also be the same when three types of suction bodies 11 to 13 are used. In the following, the case in which the sheet metal is adsorbed simultaneously by all the activated suction bodies will be described, but it is also possible to control it in a different way, such as adsorbing the sheet metal with some of the suction bodies first, and then starting the adsorption by the other suction bodies.

[0038] The two types of adsorbents 11 and 13 come into contact with the top plate material and are adsorbed to the upper surface of the plate material, and then the adsorption moving unit 10 is moved upward. As the plate material is lifted by the movement of the adsorption moving unit 10, a situation may occur where the second plate material rises up in close contact with the top first plate material, as shown in Figure 2(B).

[0039] In contrast, the suction movement unit 10 is equipped with a pressing force application mechanism 21, which operates to move the pressing body 22 downward when the suction movement unit 10 has risen by a certain amount (for example, 5 cm). When the central part of the plate material is pressed by the pressing body 22, the plate material curves further as the central part is displaced downward from its original state supported by the main suction body 11 and the one-sided auxiliary suction body 13. At this time, the first plate material maintains its curved shape with both the left and right sides adsorbed to the main suction body 11, and the second plate material is subjected to an action that causes its ends to move downward due to an increase in elastic force (restoring force) against deformation. As a result, a gap is created between the first and second plate material, and the second plate material falls downward as if peeling off from the first, making it possible to lift only the top first plate material.

[0040] Thus, the pressing force application mechanism 21 is a mechanism that can further increase the amount of deformation of the lifted plate material, and can be used to separate and lift only the first plate material when the plate material is hard and difficult to deform and separate using only the suction force of the adsorbents 11 and 13. Note that the amount of movement of the pressing body 22 and the pressing force will differ depending on the material, thickness, and size of the plate material, but by conducting tests in advance, the amount of movement and pressing force of the pressing body 22 suitable for various types of plate material can be estimated and set as specifications. Furthermore, the pressing force application mechanism 21 and control device of the plate material moving device can be configured so that two or more settings can be changed depending on the plate material being moved.

[0041] Figure 3 illustrates the operation of lifting a plate using the auxiliary suction body 13 on one side. Figure 3(A) illustrates the state in which the suction moving unit 10 is in contact with the upper surface of the plate and has been raised by a certain amount.

[0042] As the plate rises, as shown in Figure 3(A), when viewed from the front, the plate curves and flexes so that the center is slightly lower and both outer sides are higher. Also, as shown in Figure 3(B), when viewed from the left, the auxiliary suction body 13 positioned on the rear side moves above the main suction body 11, and the plate curves and flexes so that only the rear side is higher and the front part is approximately horizontal. Regarding the height of the four corners of the plate, the left rear side where the auxiliary suction body 13 is installed tends to be positioned significantly higher, and as shown by the dashed line in Figure 3(A), when viewed from the front, the left side tends to be positioned higher than the right side, with the right front side being the lowest.

[0043] Thus, since one of the two main adsorbents 11, which are arranged symmetrically, has one auxiliary adsorbent 13 positioned behind the other (left side), when the plate is lifted with the center of the plate as the reference position, the plate will bend asymmetrically in multiple directions, including the length direction and the width direction (direction perpendicular to the length direction). As a result, when the plate is lifted by applying suction force to the top surface of the first plate, the deformation of the plate becomes irregular, making it easier to create areas where air can easily enter.

[0044] Furthermore, the main suction body 11 is supported by the frame member 14 via a tilting mechanism that allows it to tilt in the left-right direction, and is configured to be difficult or impossible to tilt in the front-rear direction compared to the left-right tilting motion. This makes it easier for deformation of the plate material to occur based on the suction force of the auxiliary suction body 13 on one side, and this also makes it easier to create irregular shapes in the bending deformation of the plate material, thereby creating areas where air can easily enter.

[0045] Here, regarding the placement position and suction force (adsorption force) of the one-sided auxiliary adsorbent 13, the settings required to separate the plate material will differ depending on the material, thickness, and size of the plate material. However, by conducting tests in advance, it is possible to set the placement position and suction force (adsorption force) of the one-sided auxiliary adsorbent 13 to be suitable for various types of plate material. Furthermore, the placement position and suction force of the one-sided auxiliary adsorbent 13 can be set to be changed according to the moving plate material, and the control of the control device can also be set accordingly.

[0046] Furthermore, even when lifting a large plate material as shown in Figure 4 using the suction moving unit 10, the plate material can be easily separated by utilizing the bending deformation of the plate material caused by either or both of the following: the suction force between the main adsorbent 11 and the outer auxiliary adsorbent 12, the pressing action using the pressing body 22 by the pressing force applying mechanism 21, and the suction force of the one-sided auxiliary adsorbent 13.

[0047] It should be noted that the present invention is not limited to the embodiments described above, and it can be easily inferred that various improvements and modifications are possible without departing from the spirit of the invention. For example, it may be implemented in the following modified form.

[0048] In the above embodiment, the case in which the one-sided auxiliary adsorbent 13 is installed at a position corresponding to the rear side of the main adsorbent 11 was described. However, the system is not limited to this, and the one-sided auxiliary adsorbent 13 may be installed at a different position, such as being installed so that it is located behind the outer auxiliary adsorbent 12. Furthermore, although the example was given in which the three types of adsorbents 11 to 13 are composed of one adsorption pad each, one or more of each adsorbent 11 to 13 may be composed of multiple adsorption pads.

[0049] Furthermore, although the above embodiment described a case in which the plate material is lifted while both the main adsorbent 11 and the one-sided auxiliary adsorbent 13 are generating suction force, the invention is not limited to this, and the plate material can be moved using the suction force of some of the adsorbents. For example, for a small plate material, the plate material can be lifted and moved using the operation of the pressing body 22 by the pressing force applying mechanism 21, with only the main adsorbent 11 generating suction force and the outer auxiliary adsorbent 12 and the one-sided auxiliary adsorbent 13 not generating suction force.

[0050] Furthermore, although the above embodiment describes a case in which the pressing force application mechanism 21 is operated once when the plate material is lifted by a certain amount, the plate material moving device may be configured to include control that operates the pressing force application mechanism 21 so that multiple pressing forces are applied to the upper surface of the plate material when the plate material is lifted. Alternatively, the pressing force application mechanism 21 may be configured to curve the plate material by installing a pressing body 22 using a spring so that the upper surface of the plate material is always pushed downward by the spring force. [Industrial applicability]
