Description

  The present invention relates to a glove and a glove unit for a cargo handling equipment, and to a cargo handling equipment using the glove or the glove unit.

  For example, the load can be easily lifted and lowered by a driving force of a hydraulic cylinder or the like by suspending the load on the lifting part of an arm-type or hoist-type cargo handling material carrier. In that case, the work glove (working glove) which has an operation switch for raising / lowering the raising / lowering part of a cargo handling material carrier may be used (refer patent document 1). Further, in such a cargo handling equipment, the lifting force by which the operator lifts the load suspended in the lifting unit in the antigravity direction and the lifting force by which the lifting unit lifts the load are balanced with the weight of the load. The baggage can be moved up and down more easily. At that time, a work glove (working glove) having a detection unit for detecting gripping force and lifting force when gripping and lifting the load is held by the lifting / lowering part of the cargo handling equipment and attached to the operator's hand. (See Patent Document 2).

JP-A 49-118148 Japanese Patent Laid-Open No. 2005-1870

  According to the techniques disclosed in these, compared to a case where the operator operates an operation tool such as an operation lever installed in the operation box, the switch and the detection unit are in close proximity to the operator's intention from a close distance. There is an advantage that it can be operated. On the other hand, if the operator's attention is concentrated (directed) on the operation of these switches and detectors, the attention to the gripping and movement of the baggage will be distracted, and the gripping of the baggage rather than the case of operating with bare hands. May become unstable.

  An object of the present invention is to reduce the lifting force by generating a lifting force intended by the operator according to the gripping force detected by the detection unit by stably holding the load suspended by the lifting unit. It is an object of the present invention to provide a load handling material carrying glove, a cargo handling material carrying glove unit, and a cargo handling machine using these.

Means for Solving the Problems and Effects of the Invention

In order to solve the above-mentioned problem, a glove for a material handling equipment according to the present invention includes:
In a cargo handling equipment for moving a load up and down by balancing the lifting force by which an operator lifts the load suspended in the lifting unit in the antigravity direction and the lifting force by which the lifting unit lifts the load with the weight of the load A glove having a detection unit that is held by the lifting unit and is attached to an operator's hand and detects a gripping force when gripping a load,
The gripping part where the operator grips the load is
The fabric that forms the subject,
An outer member that is arranged on the contact side with the luggage with respect to the fabric, is formed in a plate shape or a sheet shape, and contacts the luggage;
Arranged on the contact side of the operator's palm with respect to the fabric, formed in a plate shape or a sheet shape, including at least an inner member that contacts the fingers of the operator,
In the gripping portion, the outer member and the inner member are integrally formed with the cloth interposed therebetween, and when gripping the load, the outer member and the inner member are prevented from slipping, and the detection portion grips the load. The gripping force is detected, and the lifting force and / or the lifting speed can be adjusted.

  As described above, in the gripping part of the cargo handling equipment glove, the outer member functions as a slip stopper between the outer member and the finger and the inner member between the fingers. In addition, the outer member and the inner member are integrally formed in a laminated manner with the cloth interposed therebetween, and the gripping portion is reinforced by such a three-layer structure. Therefore, the lifting force intended by the operator can be generated according to the gripping force detected by the detection unit to reduce the lifting force by stably holding the load suspended by the lifting unit with the gripping unit. it can.

  As described above, the globe for a material handling equipment according to the present invention is mainly used for moving parts, semi-finished products, products, jigs, etc. in a manufacturing plant, and moving materials and tools at a civil engineering / construction site. At times, it is held by the lifting / lowering part of the material handling machine and mounted on the operator's hand. At that time, the package (object to be transported) can be held and transported as it is or in a state of being wrapped in a box, bag, wrapping paper or the like. Therefore, it can be used in a wide range of applications other than those described above. For example, it can also be used for moving a patient or the like in the field of medical care or nursing care.

  At that time, it is desirable that the outer member and the inner member are laminated and integrated by bonding by sandwiching the fabric with a material having a larger coefficient of friction than the fabric. In this way, the gripping part is further strengthened by integrating the three-layer structure by bonding. In addition, since the friction coefficient of the outer member and the inner member that come in contact with the load and the fingers is larger than that of the cloth, the load suspended from the lifting portion can be more stably gripped. By these, the safety | security and favorable operativity of the holding | grip of the load by a holding part are ensured.

  In addition, when the friction coefficient of the outer member in contact with the load is set larger than the friction coefficient of the inner member in contact with the finger, the safety of gripping the load is further enhanced. In addition, when the inner member is made thinner than the outer member, the durability of the outer member in contact with the load is improved, and the operability (operation feeling) of the inner member in contact with the fingers is improved. Can be achieved at the same time.

  Therefore, the outer member can be made of a synthetic rubber material such as acrylonitrile-butadiene rubber (NBR). The inner member can be made of a polymer material such as silicone.

  By the way, the fabric of the gripping part is composed of a reinforced fabric using high-strength and high-modulus fibers such as aramid fiber, carbon fiber, glass fiber, etc., and around the back of the hand, it is cylindrical with respect to the gripping part at both ends. Or in order to comprise the contact member which contacts the back of the hand in the connection part connected in a bag shape, it may be extended and formed along the back of the hand. By using such high-strength and high-modulus fibers for the dough of the gripping part where a gripping force for gripping the load mainly acts and the contact member of the connecting part where the lifting force for lifting the load acts Both safety and durability of the glove can be improved.

In addition, the following can be illustrated as a high intensity | strength and high elasticity fiber used for the cloth | dough of a holding part, and the contact member of a connection part.
・ "Torayca" [Toray registered trademark] (carbon fiber);
・ "Kevlar", "Nomex" [both are registered trademarks of DuPont] (aramid fiber);
"Twaron", "Technora", "Comex" [all Teijin registered trademarks] (aramid fiber);
"Vectran" [Kuraray registered trademark] (fully aromatic polyester fiber);
"Econol" [registered trademark of Sumitomo Chemical Industry] (fully aromatic polyester fiber).

  In addition, a reinforcing member that is integrated with the grip portion in a stacked manner and contacts the palm may be disposed on the contact side of the inner member constituting the grip portion with the palm. As a result, a reinforcing member is added to the above-described three-layered gripping portion, and the gripping portion is further strengthened by a convenient four-layer integrated structure, thereby improving safety. The reinforcing member can be easily and firmly integrated with the grip portion having the three-layer structure by sewing.

  Such a reinforcing member of the gripping part is partly excised, and the detecting part can be detachably attached to the inner member exposed from the excised part of the reinforcing member via an attaching member such as a hook-and-loop fastener. Thus, since the detection unit is detachable with respect to the inner member of the gripping unit, if only the detection unit is mounted (replaced) on a glove prepared for each work, for each load, and / or for each worker, The cargo handling work can be started immediately. Therefore, the working efficiency can be dramatically improved.

  By the way, the reinforcing member of the gripping part is composed of a reinforced cloth using high-strength and high-modulus fibers such as aramid fiber, carbon fiber, glass fiber, etc. In order to form a contact member that comes into contact with the back of the hand at a connection portion connected in the form of a bag or a bag, it may be extended along the back of the hand. Use such high-strength and high-modulus fiber mainly for the reinforcing member of the gripping part where the gripping force for gripping the load acts and the contact member of the connecting part where the lifting force for lifting the load acts Can improve both safety and durability of the glove. Examples of the high-strength and high-modulus fiber used for the reinforcing member of the gripping part and the contact member of the connecting part can be the same as the cloth of the gripping part described above.

  The contact member of the connecting portion described above is partially excised corresponding to the back of the hand, and outside the contact member, heat and water vapor are allowed to flow, and moisture flow is prevented or suppressed. It is preferable that a back member made of a moisture permeable / waterproof material capable of being formed integrally with the contact member. By configuring the back member with moisture permeable and waterproof material, it is possible to eliminate the stuffiness in the inner space of the glove surrounded by the gripping part and the connection part, so the operator can wear the glove in his hand and keep it for a long time You can continue working in a comfortable environment.

  Examples of moisture permeable and waterproof materials used for the back member include “Fusion” [Asahi Kasei registered trademark], “Gore-Tex” [Gore-Tex company registered trademark], and the like. In particular, the air permeability is further improved by knitting these materials into a mesh shape.

  Further on the outside of the back of the hand of such a connection part, a loop member that goes around the outside and is connected to the gripping part and the connection part in an annular shape at both ends is arranged, and the lower end part of the elevating part is interposed through the loop member The gripping part is connected so that its posture can be freely changed sideways, upwards, downwards, etc., and the connecting position of the loop member relative to the lifting part can be moved following the posture change of the operator's hand holding the load It is desirable that For example, when the operator rotates his / her wrist, the connection position of the loop member with respect to the lifting / lowering part can be moved following the posture change of the gripping part. Therefore, even if the size, shape, weight, etc. of the luggage are different, the operator Can hold the load in a comfortable working posture.

Next, in order to solve the above-mentioned problem, the globe unit for cargo handling equipment according to the present invention includes:
The above-mentioned gloves for cargo handling equipment and the gloves for cargo handling equipment configured by removing the detection unit from them are used in combination, one for the right hand and the other for the left hand. It is characterized by that.

  As described above, for example, the manufacturing cost can be reduced by attaching the detection unit to only one of the left and right gloves according to the work content or the dominant hand of the worker. Further, since the detection signal is output only from one hand side, signal processing and calculation processing can be simplified, and the glove unit and thus the cargo handling equipment transporter can be provided at low cost.

Furthermore, in order to solve the said subject, the cargo handling material carrier which concerns on this invention is the following.
The above-mentioned glove for a cargo handling equipment carrier or a pair of glove units for a cargo handling equipment carrier, which is held by an elevating unit and attached to an operator's hand, is used.
It is characterized in that the lifting force and / or the lifting speed can be adjusted by detecting the gripping force for gripping the load by the detection unit.

  As a result, one-hand specification of one glove (with a detection unit), two-hand specification of two gloves (with a detection unit on both sides), and two gloves, depending on the use of the cargo handling equipment or the work content. The two-handed specification (with the one-side detection unit) (glove unit) can be used properly, and the application range is widened.

(Example 1)
Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view illustrating a cargo handling operation using a globe unit and a cargo handling machine according to the present invention, and FIG. 2 is a partially enlarged view thereof. As shown in FIG. 1, when an operator lifts a load L (a cargo handling object; an object to be transported) suspended from a lifting arm 5 (a lifting part) of the cargo handling machine 1 in the antigravity direction, the lifting arm 5 Then, a lifting force for lifting the luggage L is generated. At this time, the load L can be easily moved up and down by balancing the lifting force of the operator and the lifting force of the lifting arm with the weight of the load, that is, by assisting the lifting force by the lifting force.

  Specifically, the swivel base 3 is supported on the pedestal 2, and the lifting arm 5 is attached to the main body 4 fixedly arranged on the swivel base 3. A pair of suspension belts 7 and 7 (connectors) that can move along the bifurcated suspension frame 6 and the distal ends of the suspension belts 7 and 7 are provided at the distal end (lower end) of the lifting arm 5. Glove unit 10 (loading material carrier) consisting of a pair of left and right gloves 10L, 10R (glove for cargo handling equipment; see FIG. 4) via hooks 8, 8 (connectors) attached to the portion (lower end). Glove unit) is suspended and held.

  As shown in FIG. 2, any one glove (for example, the right hand glove 10 </ b> R) constituting the glove unit 10 includes a detection unit 20 that detects a gripping force when gripping the luggage L. During the cargo handling operation, the glove unit 10 is used while being attached to the operator's hand H, and the lifting force or the lifting speed is adjusted by detecting the gripping force for gripping the load L by the detection unit 20 of the right hand glove 10R. Is possible.

  FIG. 3 shows a control block diagram of the cargo handling equipment. The control unit 30 of the cargo handling machine 1 calculates a lifting force (assist force) and an ascending speed corresponding to the gripping force detected by the detection unit 20 of the right hand glove 10R, and drives and controls the switching valve 40. Output a control signal. The pneumatic cylinder 50 (elevating cylinder) moves the elevating arm 5 up and down according to the amount of air (air pressure) supplied by driving control of the switching valve 40.

  For example, when the operator lifts the luggage L in the antigravity direction, the gripping force by the detection unit 20 is increased (relatively large) and detected. Accordingly, the control unit 30 drives and controls the switching valve 40 from the a position to the b position so as to generate a lifting force and a rising speed corresponding to the degree of increase in the gripping force, and operates the pneumatic cylinder 50 to Raise the load L. On the other hand, when the operator drops the luggage L in the direction of gravity, the gripping force by the detection unit 20 is detected to be reduced (as opposed to being small). Accordingly, the control unit 30 drives and controls the switching valve 40 from the a position to the c position so as to generate a negative lifting force and a descending speed corresponding to the degree of decrease in the gripping force, and operates the pneumatic cylinder 50 to move the lifting arm. At 5, the load L is lowered.

  Next, FIG. 4 is a front view showing an example of a glove unit according to the present invention, FIG. 5 is a rear view thereof, FIG. 6 is a cross-sectional view of a grip part and a connection part of a right-hand glove, and FIG. It is. As shown in FIGS. 4 and 5, the left and right gloves 10L and 10R constituting the glove unit 10 respectively travel around the gripping portion 11 where the operator grips the luggage L and the outside of the back of the hand HB (see FIG. 6). And a connecting portion 12 connected to the grip portion 11 in a cylindrical shape (or a bag shape in which the tip side of the finger HF at the tip of the palm HP is closed in FIG. 6B). Each globe 10L, 10R has a loop member 13 that is connected to the gripping portion 11 and the connecting portion 12 at both ends around the outside of the back of the hand HB, and connected to the gripping portion 11 and the connecting portion 12 at both ends. Are arranged (see FIG. 6A).

  As shown in FIG. 6, the gripping portion 11 of each of the gloves 10L and 10R has an outer member 112 disposed on the contact side with the luggage L with respect to the fabric 111 with the fabric 111 constituting the main body interposed therebetween, and the fabric 111 On the other hand, the inner member 113 arranged on the contact side of the operator's palm HP and the finger HF is laminated and integrated by an adhesive layer 115, respectively. The fabric 111 of the gripping part 11 is made of a reinforced fabric using high-strength and high-modulus fibers (for example, carbon fiber, specifically “Torayca” [Toray registered trademark], etc.), and the safety of the gloves 10L and 10R. And increased durability. The outer member 112 is formed in a plate shape (or a sheet shape) from a synthetic rubber material (for example, acrylonitrile-butadiene rubber (NBR)), and is in direct contact with the load L. The inner member 113 is formed in a plate shape (or a sheet shape) from a polymer material (for example, silicone) and directly contacts the operator's finger HF.

  As described above, when gripping the luggage L, the outer member 112 functions as a slip stopper between the outer member 112 and the luggage L, while the inner member 113 functions as an anti-slip between the operator's fingers HF. Further, since the outer member 112 and the inner member 113 are integrally formed in a three-layered structure with the fabric 111 interposed therebetween, the gripping portion 11 is strengthened and the luggage L suspended from the lifting arm 5 (see FIG. 1). Is stably gripped by the gripping unit 11, the lifting force intended by the operator can be generated according to the gripping force detected by the detection unit 20, and the lifting force can be reduced. Furthermore, since the friction coefficient of the outer member 112 in contact with the luggage L and the inner member 113 in contact with the operator's finger HF is larger than the friction coefficient of the cloth 111, the luggage L suspended from the lifting arm 5 is removed. It can be gripped more stably.

  Since the friction coefficient of the outer member 112 in contact with the luggage L is set to be larger than the friction coefficient of the inner member 113 in contact with the finger HF, the safety of gripping the luggage L is further enhanced. Moreover, since the thickness of the inner member 113 is formed thinner than the thickness of the outer member 112, the durability of the outer member 112 in contact with the luggage L is improved, and the operability in the inner member 113 in contact with the finger HF ( Improvement of operation feeling can be achieved at the same time.

  A reinforcing member 114 that is in direct contact with the palm HP is sewn together with the above-described three-layer structure on the inner side (that is, the side of the inner member 113 in contact with the palm HP) so as to be integrated in a laminated manner. Is formed. That is, the palm HP portion of the gripping portions 11 of the globes 10 </ b> L and 10 </ b> R is integrally configured in a four-layered structure including the reinforcing member 114. The reinforcing member 114 is formed of a reinforced cloth using high-strength and high-modulus fibers (for example, carbon fiber, specifically “Torayca” [Toray registered trademark], etc.) as in the case of the fabric 111. Thus, the palm HP portion of the gripping portion 11 is further strengthened by the four-layer integrated structure, and the gripping force can be detected by safely gripping the luggage L over a long period of time.

  By the way, in the reinforcing member 114 of the right hand glove 10R, the contact portion with the palm HP in the vicinity of the base of the right hand little finger is excised (removed portion 114a; see FIG. 4). And the above-mentioned detection part 20 is mounted | worn so that attachment or detachment is possible via the hook-and-loop fastener 25 (mounting member) ranging over the inner member 113 and the reinforcement member 114 exposed from the cutting part 114a (refer FIG. 4). Similarly, the above-described detection unit 20 is detachably mounted on the inner member 113 at the contact portion with the finger HF near the base of the right index finger (see FIG. 4). In this way, when lifting or suspending or pinching the luggage L with the hand H, the vicinity of the base of the little finger and the vicinity of the index finger are the parts that naturally exert force (force is applied) to grip the luggage L. Since each detecting unit 20 is provided correspondingly, the gripping force of the operator can be detected with high sensitivity.

  Further, the reinforcing member 114 of the grip portion 11 of each globe 10L, 10R is extended along the back of the hand HB in order to form a contact member 121 that contacts the back of the hand HB at the connecting portion 12. Then, the contact member 121 of the connecting portion 12 is partially excised corresponding to the back of the hand HB (the excised portion 121a; see FIG. 5), and the back member 122 is connected to the contact member 121 outside the contact member 121. They are stitched together and integrally formed in a laminated form. The back member 122 knits a moisture-permeable / water-proof material (for example, “Fusion” [Asahi Kasei Registered Trademark], etc.) that allows the flow of heat and water vapor and prevents or suppress the flow of moisture into a mesh shape. The air permeability is improved.

  The fabric 111 and the reinforcing member 114 of the grip portion 11 on which a gripping force mainly for gripping the load L acts, and the contact member 121 of the connection portion 12 on which a lifting force for lifting the load L acts on such a high height. By using the strength / high modulus fiber, both the safety and durability of the gloves 10L and 10R can be improved. Further, by configuring the back member 122 with a moisture permeable and waterproof material, it is possible to eliminate the stuffiness in the internal space of each of the gloves 10L and 10R surrounded by the grip portion 11 and the connection portion 12. Therefore, even when the gloves 10L and 10R are attached to both hands H and continuous work is performed for a long time, the worker can continue working in a safe and comfortable environment.

  Further, the loop member 13 is suspended via a hook 8 so that the gripping portion 11 can change its posture in a lateral direction, an upward direction, a downward direction, or the like with respect to the suspension belt 7 connected to the lower end portion of the elevating arm 5. It is held down (see FIG. 1). That is, the connection position of the loop member 13 with respect to the lifting arm 5 can be moved following the posture change of the hand H of the operator holding the luggage L. Therefore, for example, if the operator rotates the hand H (wrist), the connection position of the loop member 13 can be moved along with the change in the posture of the gripping part 11, so that the size, shape, weight, etc. of the luggage L can be increased. Even if they are different, the operator can grip the load L with a comfortable working posture.

  As shown in FIG. 7, each detection unit 20, 20 attached to the right hand glove 10 </ b> R includes a pressure sensor 21 disposed on the side of the gripping unit 11 in contact with the palm HP, and a pressure sensor 21 directly on the pressure-sensitive surface side. (Or indirectly in a container such as a bag) and a pressure-sensitive adjusting unit 22 disposed in contact with the pressure sensor 21, and a sensor substrate 23 disposed on the side opposite to the pressure-sensitive surface side of the pressure sensor 21. Yes. The pressure sensor 21 is configured by a plate-shaped (or sheet-shaped) pressure-sensitive sensor that detects a change in electrical resistance due to the application of a gripping force via the pressure-sensitive adjustment unit 22. The pressure-sensitive adjusting unit 22 is formed in a gel containing unit that includes a gel-like material (for example, silicone) that is an elastically deformable semi-solid polymer material, and covers the entire pressure-sensitive surface of the pressure sensor 21. The sensor substrate 23 has a lead wire W (signal line) for mounting the pressure sensor 21 and outputting a detection signal detected by the pressure sensor 21 to the outside. And the pressure sensor 21, the pressure sensitive adjustment part 22, and the sensor board | substrate 23 are surrounded by the protection member 24, and the detection part 20 wrapped in this way by the protection member 24 is via the surface fastener 25 (mounting member), The grip 11 is detachably mounted.

  In this way, the pressure sensor 21 of the detection unit 20 corresponds to the vicinity of the base of the index finger on the palm HP side and the vicinity of the base of the little finger, which are portions that naturally generate force (force is applied) in order to grip the luggage L. Therefore, it is possible to detect with high sensitivity the gripping force when the baggage L is lifted, hung or pinched with both hands H. Further, since the pressure-sensitive adjusting portion 22 is made of a gel-like material such as silicone, and the gel-like material covers the entire pressure-sensitive surface of the pressure sensor 21, it is spread over the entire pressure-sensitive surface when receiving a gripping force. Almost the whole can be deformed to receive the gripping force. As a result, the pressure sensor 21 (detection unit 20) can obtain a uniform (uniform and flat) output signal distribution over the entire pressure-sensitive surface and reduce the difference (deviation) in the detected pressure due to the position of the pressure-sensitive surface. And the detection of gripping force is stable.

  Furthermore, since the detection unit 20 covered with the protective member 24 is detachable from the gripping unit 11, only the detection unit 20 (pressure sensor 21) is provided in the glove 10 prepared for each work, for each load, and for each worker. If the item is mounted (replaced), the material handling work can be started immediately and the work efficiency can be improved. When the protective member 24 is made of the moisture permeable and waterproof material (for example, “Fusion” [Asahi Kasei registered trademark]) used for the back member 122 (see FIG. 6) described above, Since it is possible to prevent (suppress) the intrusion of moisture such as perspiration into the detection unit 20, it is possible to prevent the signal output from the pressure sensor 21 from being interrupted due to an electrical short circuit.

(Example 2)
Next, FIG. 8 is a front view showing another example of the glove unit according to the present invention, FIG. 9 is a rear view thereof, and FIG. 10 is a cross-sectional view of a grip part and a connection part of a right hand glove. As shown in FIGS. 8 and 9, the left and right gloves 10L ′ and 10R ′ (the cargo handling equipment glove) constituting the glove unit 10 ′ (the handling equipment transporting glove unit) are respectively loaded by the operator with the load L. And a gripping portion 11 that wraps around the outside of the back of the hand HB (see FIG. 10) with respect to the gripping portion 11 at both ends (or a bag shape in which the tip side of the finger HF at the tip of the palm HP in FIG. 10 is closed) And a connecting portion 12 to be connected. In addition, a direction changing member 14 (attachment member) that protrudes outward from the edge and returns to the original edge is fixedly disposed at the edge of each globe 10L ′, 10R ′. Specifically, both ends of the direction changing member 14 are sewn to at least one edge of the grip portion 11 and the connection portion 12 to suspend and hold the hook 8 (connector). In this way, the hook 8 connects the suspension belt 7 (connector) connected to the lower end of the lift arm 5 (lift) and the direction changing member 14 of the gloves 10L ′ and 10R ′. (See FIG. 1).

  As shown in FIG. 10, the gripping portion 11 of each of the gloves 10L ′ and 10R ′ has an outer member 112 disposed on the contact side with the load L with respect to the fabric 111 with the fabric 111 forming the main body interposed therebetween, An inner member 113 disposed on the fabric 111 on the contact side of the operator's palm HP and fingers HF is bonded and laminated by an adhesive layer 115. Further, the fabric 111 of the grip portion 11 of each glove 10L ′, 10R ′ is extended along the back of the hand HB to form a contact member 121 that contacts the back of the hand HB at the connecting portion 12. Then, the contact member 121 of the connecting portion 12 is partially excised corresponding to the back of the hand HB (the excised portion 121a; see FIG. 9), and the back member 122 is connected to the contact member 121 outside the contact member 121. They are stitched together and integrally formed in a laminated form.

  High-strength and high-elastic modulus fibers are mainly applied to the fabric 111 of the grip portion 11 on which a gripping force for gripping the load L acts and the contact member 121 of the connecting portion 12 on which a lifting force for lifting the load L acts. By using it, both the safety and durability of the gloves 10L ′ and 10R ′ can be enhanced. Further, by forming the back member 122 from a moisture permeable and waterproof material, it is possible to eliminate the stuffiness in the internal space of each of the gloves 10L 'and 10R' surrounded by the grip portion 11 and the connection portion 12. Therefore, even when the gloves 10L 'and 10R' are attached to both hands H and the continuous work is performed for a long time, the worker can continue the work in a safe and comfortable environment.

  As shown in FIG. 10, the detection unit 20 ′ attached to the right-hand glove 10 </ b> R ′ is arranged at the connection unit 12 and the pressure-sensitive adjustment unit 22 ′ arranged on the contact side of the gripping unit 11 with the palm HP. And a pressure sensor 21 '. The pressure-sensitive adjusting unit 22 ′ is formed in an air-filled bag (fluid-filled bag) filled with a predetermined pressure of fluid having fluidity (pressure-measuring fluid), and is wide enough to be in contact with the entire surface of the palm HP. And is attached to the inner member 113 of the grip portion 11. The pressure sensor 21 ′ communicates with the pressure sensitive adjustment unit 22 ′ via a tube 26 (communication pipe), and detects a change in the internal pressure of the pressure sensitive adjustment unit 22 ′ when a gripping force is applied ( The fluid pressure sensor is mounted on the outer surface of the back member 122. The detection unit 20 'does not require a sensor board, and a lead wire W (signal line) for outputting a detection signal to the outside extends from the pressure sensor 21'.

  As described above, since air for pressure measurement is used as it is as a fluid fluid contained in the pressure-sensitive adjustment unit 22 ′, the configuration of the detection unit 20 ′ is simplified, and when the gripping force of the operator is applied, The pressure can be smoothly transmitted to the pressure sensor 21 ', and a signal can be output in a wide range. Further, even if the pressure-sensitive adjusting portion 22 ′ disposed on the side of the gripping portion 11 in contact with the palm HP is widely formed so as to cover the entire surface of the palm HP, the pressure sensor 21 ′ is disposed at the connection portion 12. Accordingly, the gripping portion 11 can be formed relatively thin. Since the pressure-sensitive adjusting unit 22 ′ is filled with air, the pressure-sensitive area is substantially enlarged, the output signals are equalized, and a stable sensor output can be obtained. In addition, since the feeling of gripping the luggage L and pressing the pressure-sensitive adjusting portion 22 'is transmitted to the operator via the air, the operability is also improved.

  In the second embodiment (FIGS. 8 to 10), parts having the same functions as those in the first embodiment (FIGS. 4 to 7) are denoted by the same reference numerals and description thereof is omitted.

In the above example,
(1) Glove unit specifications combining a right hand glove with a detector and a left hand glove without a detector;
The case where is used has been described. In this specification, for example, the manufacturing cost can be reduced by attaching the detection unit to only one of the left and right gloves according to the work content or the dominant hand of the worker. Further, since the detection signal is output only from one hand side, signal processing and calculation processing can be simplified, and the glove unit and thus the cargo handling equipment transporter can be provided at low cost.

Or
(2) One-handed glove specification with detector;
(3) Glove specifications with a pair of detectors;
May be used. Among these, in the case of a one-handed glove specification with a detection part, the cheapest glove for a cargo handling equipment carrier can be provided. On the other hand, in the case of a glove specification with a pair of detection units, even if a failure or the like occurs in one detection unit, the gripping force can be detected by the other detection unit, and safety is improved.

  And if each detection part can be attached or detached to any glove (gripping part), it was described above according to the use of the cargo handling equipment or according to the work contents (1) to (3). Each specification can be used properly, and the range of application becomes even wider.

  In the present invention, in addition to the mittens type glove described in the embodiment, the finger HF portion is formed in a bag shape for each finger, and the grip portion 11 and the connection portion 12 are formed in a cylindrical shape. It can also be applied to a glove that does not have (not protects) a finger HF portion.
